+New features with this release, as extensions of the Apache functionality
+(see also more detailed CHANGES file) in the source directory. For more
+information, see http://www.apache.org/docs/1.1/
+
+In addition to a number of bug fixes and internal performance
+enhancements, Apache 1.1 has the following specific new user
+features:
+
+ *) Caching Proxy Server
+ Apache can now act as an HTTP proxy server, allowing clients
+ behind firewalls to use the server to access the outside world. In
+ addition, it can cache documents it proxies, speeding up access to
+ frequently requested documents.
+
+ *) Filetype-based Script "Actions"
+ You can now run CGI scripts whenever a file of a certion type is
+ requested. Makes it much easier to execute scripts that process
+ files.
+
+ *) Support for Keep-Alive Persistent Connections
+ Apache now has (optional) support for persistent connections, as
+ defined by the HTTP/1.1 draft. This protocol, supported by a
+ number of current HTTP servers and browsers (including Netscape
+ Navigator 2.0) has been shown to increase speed of document
+ transfer by up to 50% in certain cases.
+
+ *) Customizable CGI Environment Variables (not in this release)
+ New PassEnv and SetEnv directives allow you to modify the
+ environment variables passed to CGI scripts
+
+ *) CERN Metafile Support
+ Now emulates the CERN httpd's support for metafiles containing
+ additional HTTP headers to be supplied with a document.
+
+ *) Redirect Now Usable in .htaccess Files
+ The Redirect directive can now be used in .htaccess files when the
+ FileInfo directive has been set on. This allows users to redirect
+ parts of their directories without requiring CGI scripts
+
+ *) Improved UserDir Directive (not in this release)
+ Now supports the ability to point user's files (as specificed by
+ URLs beginning with the "~" character) at directories other than
+ those specified by the Unix password file.
+
+ *) Minimal DNS Now Runtime Option
+ New HostnameLookups server configuration directive can be used to
+ turn On or Off DNS lookups. This supercedes the -DMINIMAL_DNS
+ compile-time configuration option.
+
+ *) Listen to Multiple Addresses and Ports
+ Using the new Listen directive, Apache can listen to more than one
+ port and IP address, using the same configuration set.
+
+ *) Anonymous HTTP Logins
+ New options allow you to allow, using Basic HTTP Authentication,
+ anonymous logins, like those of FTP. This allows you to collect
+ email addresses of people accessing your site.
+
+ *) File Owner Avialable to Included CGI Scripts
+ Server-side includes that call CGI scripts will now set a
+ USER_NAME environment variable that contains the owner of the file
+ which included it.
+
+ *) Improved Icons
+ Thanks to Kevin Hughes, Apache's nifty color GIF icons for
+ directory listings have been updated. In addition, the Powered by
+ Apache (apache_pb.gif) logo has been included.
+
+ *) Log Rotation
+ New support utility to allow log rotation without shutting down the
+ server. See support/rotatelogs.c.
+
+NEW AUTHENTICATION MODULES:
+
+Note: These modules are not compiled into the server by default, as
+they require special support on the host system. They must be enabled
+specifically in the Configuration file.
+
+ *) Support for Unix DB Authentication - mod_db.c
+ In addition to DBM support, Apache now contains optional support
+ for Berkeley DB databases.
+
+ *) mSQL Database Authentication - mod_auth_msql.html
+ Support for the use of mSQL databases for user authentication via
+ HTTP is now supported.

+ Apache
+ Version 1.1 (and up)
+
+What is it?
+-----------
+
+Apache is an HTTP server designed as a plug-in replacement for the NCSA
+server version 1.3 (or 1.4). It fixes numerous bugs in the NCSA server and
+includes many frequently requested new features, and has an API which
+allows it to be extended to meet users' needs more easily.
+
+Documentation
+-------------
+
+All the documentation is on-line on the WWW, via .
+
+Installation
+------------
+
+Unless you grabbed a binary distribution of Apache, you must compile
+it for your specific platform. In order to compile it, you must set
+compile-time options (in particular, system type) for your system by
+editing a Configuration file, run a script which generates a Makefile
+and a small piece of C code, and then compile it.
+
+For instructions on compilation, see the file 'INSTALL' in the src/ directory.
+
+After compilation, you will have a binary called "httpd" in the src/
+directory. If you received a binary distribution of apache, you
+should have this file already.
+
+The next step is to edit the configuration files for the server. In
+the subdirectory called "conf" you should find distribution versions
+of the three configuration files: srm.conf-dist, access.conf-dist, and
+httpd.conf-dist. Copy them to srm.conf, access.conf, httpd.conf
+respectively.
+
+First edit httpd.conf. This sets up general attributes about the
+server - the port number, the user it runs as, etc. Next edit the
+srm.conf file - this sets up the root of the document tree, special
+functions like server-parsed HTML or internal imagemap parsing, etc.
+Finally, edit the access.conf file to at least set the base cases of
+access. Documentation for all of these is located at
+.
+
+Finally, make a call to httpd, with a -f to the full path to the
+httpd.conf file. I.e., the common case:
+
+ /usr/local/etc/apache/src/httpd -f /usr/local/etc/apache/conf/httpd.conf
+
+And voila! The server should be running.
+
+By default the srm.conf and access.conf files are located by name - to
+specifically call them by other names, use the AccessConfig and
+ResourceConfig directives in httpd.conf.
+
+The Latest Version
+------------------
+
+Details of the latest version are in the apache project page (above).
+
+NOTE: At the time of release of Apache 1.1, two modules had updated
+versions which were not sufficiently tested for inclusion into the 1.1
+distribution: mod_auth_msql and mod_cern_meta. The newer versions are
+available from http://www.apache.org/dist/contrib/modules/ - if you
+plan on using this functionality we encourage you to give the newer
+modules a test drive, and let us know of any problems. In particular,
+mod_cern_meta is now configurable per-directory, and the configuration
+directives have changed. We can not promise that the existing
+configuration directives provided by the mod_cern_meta included in the
+distribution will be supported in the future.
+
+Licencing
+---------
+
+Please see the file called LICENSE.

+1. Don't commit several unrelated changes in one go. Each change should be
+committed separately (that is, it can affect multiple files, but it should all
+be part of a single change).

+2. When committing, make sure that the CVS log message explains what the
+patches do and why.

+3. Don't edit CHANGES files unless there is a change which is visible to a user
+of Apache. CVS logs provide a detailed history of all changes (if people follow

+# then use content negotiation to give a browser a file in a language
+# it can understand. Note that the suffix does not have to be the same
+# as the language keyword --- those with documents in Polish (whose

+# AddType allows you to tweak mime.types without actually editing it, or to
+# make certain files to be certain types.

+# AddHandler allows you to map certain file extensions to "handlers",
+# actions unrelated to filetype. These can be either built into the server
+# or added with the Action command (see below)
+# Format: AddHandler action-name ext1
+
+# To use CGI scripts:
+#AddHandler cgi-script .cgi
+
+# To use server-parsed HTML files
+#AddType text/html .shtml
+#AddHandler server-parsed .shtml
+
+# Uncomment the following line to enable Apache's send-asis HTTP file
+# feature
+#AddHandler send-as-is asis
+
+# If you wish to use server-parsed imagemap files, use
+#AddHandler imap-file map
+
+# To enable type maps, you might want to use
+#AddHandler type-map var

+# Action lets you define media types that will execute a script whenever
+# a matching file is called. This eliminates the need for repeated URL
+# pathnames for oft-used CGI file processors.
+# Format: Action media/type /cgi-script/location
+# Format: Action handler-name /cgi-script/location
+
+# For example to add a footer (footer.html in your document root) to
+# files with extension .foot (e.g. foo.html.foot), you could use:
+#AddHandler foot-action foot
+#Action foot-action /cgi-bin/footer
+
+# Or to do this for all HTML files, for example, use:
+#Action text/html /cgi-bin/footer
+
+# MetaDir: specifies the name of the directory in which Apache can find
+# meta information files. These files contain additional HTTP headers
+# to include when sending the document
+
+#MetaDir .web
+
+# MetaSuffix: specifies the file name suffix for the file containing the
+# meta information.
+
+#MetaSuffix .meta

+# Customizable error response (Apache style)
+# these come in three flavors
+#
+# 1) plain text

+# 2) local redirects
+#ErrorDocument 404 /missing.html
+# to redirect to local url /missing.html
+#ErrorDocument 404 /cgi-bin/missing_handler.pl
+# n.b. can redirect to a script or a document using server-side-includes.

+Public Domain Icons
+
+ These icons were originally made for Mosaic for X and have been
+ included in the NCSA httpd and Apache server distributions in the
+ past. They are in the public domain and may be freely included in any

+
+ Many thanks to Andy Polyakov for tuning the icon colors and adding a
+ few new images. If you'd like to contribute additions or ideas to
+ this set, please let me know.
+
+ The distribution site for these icons is at:

Apache API notes
+Apache API notes
+
+Robert S. Thau
+
+These are some notes on the Apache API and the data structures you
+have to deal with, etc. They are not yet nearly complete, but
+hopefully, they will help you get your bearings. Keep in mind that
+the API is still subject to change as we gain experience with it.
+(See the TODO file for what might be coming). However,
+it will be easy to adapt modules to any changes that are made.
+(We have more modules to adapt than you do).
+
+
+A few notes on general pedagogical style here. In the interest of
+conciseness, all structure declarations here are incomplete --- the
+real ones have more slots, that I'm not telling you about. For the
+most part, these are reserved to one component of the server core or
+another, and should be altered by modules with caution. However, in
+some cases, they really are things I just haven't gotten around to
+yet. Welcome to the bleeding edge.
+
+Finally, here's an outline, to give you some bare idea of what's
+coming up, and in what order:
+
+
+
+
+
+We begin with an overview of the basic concepts behind the
+API, and how they are manifested in the code.
+
+
+
+Apache breaks down request handling into a series of steps, more or
+less the same way the Netscape Server API does (although this API has
+a few more stages than NetSite does, as hooks for stuff I thought
+might be useful in the future). These are:
+
+
+ - URI -> Filename translation
+
- Auth ID checking [is the user who they say they are?]
+
- Auth access checking [is the user authorized here?]
+
- Access checking other than auth
+
- Determining MIME type of the object requested
+
- "Fixups" --- there aren't any of these yet, but the phase is
+ intended as a hook for possible extensions like
+
SetEnv, which don't really fit well elsewhere.
+ - Actually sending a response back to the client.
+
- Logging the request
+
+
+These phases are handled by looking at each of a succession of
+modules, looking to see if each of them has a handler for the
+phase, and attempting invoking it if so. The handler can typically do
+one of three things:
+
+
+ - Handle the request, and indicate that it has done so
+ by returning the magic constant
OK.
+ - Decline to handle the request, by returning the magic
+ integer constant
DECLINED. In this case, the
+ server behaves in all respects as if the handler simply hadn't
+ been there.
+ - Signal an error, by returning one of the HTTP error codes.
+ This terminates normal handling of the request, although an
+ ErrorDocument may be invoked to try to mop up, and it will be
+ logged in any case.
+
+
+Most phases are terminated by the first module that handles them;
+however, for logging, "fixups", and non-access authentication
+checking, all handlers always run (barring an error). Also, the
+response phase is unique in that modules may declare multiple handlers
+for it, via a dispatch table keyed on the MIME type of the requested
+object. Modules may declare a response-phase handler which can handle
+any request, by giving it the key */* (i.e., a
+wildcard MIME type specification). However, wildcard handlers are
+only invoked if the server has already tried and failed to find a more
+specific response handler for the MIME type of the requested object
+(either none existed, or they all declined).
+
+The handlers themselves are functions of one argument (a
+request_rec structure. vide infra), which returns an
+integer, as above.
+
+
+
+At this point, we need to explain the structure of a module. Our
+candidate will be one of the messier ones, the CGI module --- this
+handles both CGI scripts and the ScriptAlias config file
+command. It's actually a great deal more complicated than most
+modules, but if we're going to have only one example, it might as well
+be the one with its fingers in everyplace.
+
+Let's begin with handlers. In order to handle the CGI scripts, the
+module declares a response handler for them. Because of
+ScriptAlias, it also has handlers for the name
+translation phase (to recognise ScriptAliased URI's), the
+type-checking phase (any ScriptAliased request is typed
+as a CGI script).
+
+The module needs to maintain some per (virtual)
+server information, namely, the ScriptAliases in effect;
+the module structure therefore contains pointers to a functions which
+builds these structures, and to another which combines two of them (in
+case the main server and a virtual server both have
+ScriptAliases declared).
+
+Finally, this module contains code to handle the
+ScriptAlias command itself. This particular module only
+declares one command, but there could be more, so modules have
+command tables which declare their commands, and describe
+where they are permitted, and how they are to be invoked.
+
+A final note on the declared types of the arguments of some of these
+commands: a pool is a pointer to a resource pool
+structure; these are used by the server to keep track of the memory
+which has been allocated, files opened, etc., either to service a
+particular request, or to handle the process of configuring itself.
+That way, when the request is over (or, for the configuration pool,
+when the server is restarting), the memory can be freed, and the files
+closed, en masse, without anyone having to write explicit code to
+track them all down and dispose of them. Also, a
+cmd_parms structure contains various information about
+the config file being read, and other status information, which is
+sometimes of use to the function which processes a config-file command
+(such as ScriptAlias).
+
+With no further ado, the module itself:
+
+
+/* Declarations of handlers. */
+
+int translate_scriptalias (request_rec *);
+int type_scriptalias (request_rec *);
+int cgi_handler (request_rec *);
+
+/* Subsdiary dispatch table for response-phase handlers, by MIME type */
+
+handler_rec cgi_handlers[] = {
+{ "application/x-httpd-cgi", cgi_handler },
+{ NULL }
+};
+
+/* Declarations of routines to manipulate the module's configuration
+ * info. Note that these are returned, and passed in, as void *'s;
+ * the server core keeps track of them, but it doesn't, and can't,
+ * know their internal structure.
+ */
+
+void *make_cgi_server_config (pool *);
+void *merge_cgi_server_config (pool *, void *, void *);
+
+/* Declarations of routines to handle config-file commands */
+
+char *script_alias (cmd_parms *, void *per_dir_config, char *fake, char *real);
+
+command_rec cgi_cmds[] = {
+{ "ScriptAlias", script_alias, NULL, RSRC_CONF, TAKE2,
+ "a fakename and a realname"},
+{ NULL }
+};
+
+module cgi_module = {
+ STANDARD_MODULE_STUFF,
+ NULL, /* initializer */
+ NULL, /* dir config creater */
+ NULL, /* dir merger --- default is to override */
+ make_cgi_server_config, /* server config */
+ merge_cgi_server_config, /* merge server config */
+ cgi_cmds, /* command table */
+ cgi_handlers, /* handlers */
+ translate_scriptalias, /* filename translation */
+ NULL, /* check_user_id */
+ NULL, /* check auth */
+ NULL, /* check access */
+ type_scriptalias, /* type_checker */
+ NULL, /* fixups */
+ NULL /* logger */
+};
+
+
+
+
+The sole argument to handlers is a request_rec structure.
+This structure describes a particular request which has been made to
+the server, on behalf of a client. In most cases, each connection to
+the client generates only one request_rec structure.
+
+
+
+The request_rec contains pointers to a resource pool
+which will be cleared when the server is finished handling the
+request; to structures containing per-server and per-connection
+information, and most importantly, information on the request itself.
+
+The most important such information is a small set of character
+strings describing attributes of the object being requested, including
+its URI, filename, content-type and content-encoding (these being filled
+in by the translation and type-check handlers which handle the
+request, respectively).
+
+Other commonly used data items are tables giving the MIME headers on
+the client's original request, MIME headers to be sent back with the
+ppppresponse (which modules can add to at will), and environment variables
+for any subprocesses which are spawned off in the course of servicing
+the request. These tables are manipulated using the
+table_get and table_set routines.
+
+Finally, there are pointers to two data structures which, in turn,
+point to per-module configuration structures. Specifically, these
+hold pointers to the data structures which the module has built to
+describe the way it has been configured to operate in a given
+directory (via .htaccess files or
+<Directory> sections), for private data it has
+built in the course of servicing the request (so modules' handlers for
+one phase can pass "notes" to their handlers for other phases). There
+is another such configuration vector in the server_rec
+data structure pointed to by the request_rec, which
+contains per (virtual) server configuration data.
+
+Here is an abridged declaration, giving the fields most commonly used:
+
+
+struct request_rec {
+
+ pool *pool;
+ conn_rec *connection;
+ server_rec *server;
+
+ /* What object is being requested */
+
+ char *uri;
+ char *filename;
+ char *path_info;
+ char *args; /* QUERY_ARGS, if any */
+ struct stat finfo; /* Set by server core;
+ * st_mode set to zero if no such file */
+
+ char *content_type;
+ char *content_encoding;
+
+ /* MIME header environments, in and out. Also, an array containing
+ * environment variables to be passed to subprocesses, so people can
+ * write modules to add to that environment.
+ *
+ * The difference between headers_out and err_headers_out is that the
+ * latter are printed even on error, and persist across internal redirects
+ * (so the headers printed for ErrorDocument handlers will have them).
+ */
+
+ table *headers_in;
+ table *headers_out;
+ table *err_headers_out;
+ table *subprocess_env;
+
+ /* Info about the request itself... */
+
+ int header_only; /* HEAD request, as opposed to GET */
+ char *protocol; /* Protocol, as given to us, or HTTP/0.9 */
+ char *method; /* GET, HEAD, POST, etc. */
+ int method_number; /* M_GET, M_POST, etc. */
+
+ /* Info for logging */
+
+ char *the_request;
+ int bytes_sent;
+
+ /* A flag which modules can set, to indicate that the data being
+ * returned is volatile, and clients should be told not to cache it.
+ */
+
+ int no_cache;
+
+ /* Various other config info which may change with .htaccess files
+ * These are config vectors, with one void* pointer for each module
+ * (the thing pointed to being the module's business).
+ */
+
+ void *per_dir_config; /* Options set in config files, etc. */
+ void *request_config; /* Notes on *this* request */
+
+};
+
+
+
+
+
+Most request_rec structures are built by reading an HTTP
+request from a client, and filling in the fields. However, there are
+a few exceptions:
+
+
+ - If the request is to an imagemap, a type map (i.e., a
+
*.var file), or a CGI script which returned a
+ local "Location:", then the resource which the user requested
+ is going to be ultimately located by some URI other than what
+ the client originally supplied. In this case, the server does
+ an internal redirect, constructing a new
+ request_rec for the new URI, and processing it
+ almost exactly as if the client had requested the new URI
+ directly.
+
+
- If some handler signaled an error, and an
+
ErrorDocument is in scope, the same internal
+ redirect machinery comes into play.
+
+
- Finally, a handler occasionally needs to investigate "what
+ would happen if" some other request were run. For instance,
+ the directory indexing module needs to know what MIME type
+ would be assigned to a request for each directory entry, in
+ order to figure out what icon to use.
+
+ Such handlers can construct a sub-request, using the
+ functions sub_req_lookup_file and
+ sub_req_lookup_uri; this constructs a new
+ request_rec structure and processes it as you
+ would expect, up to but not including the point of actually
+ sending a response. (These functions skip over the access
+ checks if the sub-request is for a file in the same directory
+ as the original request).
+
+ (Server-side includes work by building sub-requests and then
+ actually invoking the response handler for them, via the
+ function run_sub_request).
+
+
+
+
+As discussed above, each handler, when invoked to handle a particular
+request_rec, has to return an int to
+indicate what happened. That can either be
+
+
+ - OK --- the request was handled successfully. This may or may
+ not terminate the phase.
+
- DECLINED --- no erroneous condition exists, but the module
+ declines to handle the phase; the server tries to find another.
+
- an HTTP error code, which aborts handling of the request.
+
+
+Note that if the error code returned is REDIRECT, then
+the module should put a Location in the request's
+headers_out, to indicate where the client should be
+redirected to.
+
+
+
+Handlers for most phases do their work by simply setting a few fields
+in the request_rec structure (or, in the case of access
+checkers, simply by returning the correct error code). However,
+response handlers have to actually send a request back to the client.
+
+They should begin by sending an HTTP response header, using the
+function send_http_header. (You don't have to do
+anything special to skip sending the header for HTTP/0.9 requests; the
+function figures out on its own that it shouldn't do anything). If
+the request is marked header_only, that's all they should
+do; they should return after that, without attempting any further
+output.
+
+Otherwise, they should produce a request body which responds to the
+client as appropriate. The primitives for this are rputc
+and rprintf, for internally generated output, and
+send_fd, to copy the contents of some FILE *
+straight to the client.
+
+At this point, you should more or less understand the following piece
+of code, which is the handler which handles GET requests
+which have no more specific handler; it also shows how conditional
+GETs can be handled, if it's desirable to do so in a
+particular response handler --- set_last_modified checks
+agaisnt the If-modified-since value supplied by the
+client, if annny, and returns an appropriate code (which will, if
+nonzero, be USE_LOCAL_COPY). No similar considerations apply for
+set_content_length, but it returns an error code for
+symmetry.
+
+
+int default_handler (request_rec *r)
+{
+ int errstatus;
+ FILE *f;
+
+ if (r->method_number != M_GET) return DECLINED;
+ if (r->finfo.st_mode == 0) return NOT_FOUND;
+
+ if ((errstatus = set_content_length (r, r->finfo.st_size))
+ || (errstatus = set_last_modified (r, r->finfo.st_mtime)))
+ return errstatus;
+
+ f = fopen (r->filename, "r");
+
+ if (f == NULL) {
+ log_reason("file permissions deny server access", r->filename, r);
+ return FORBIDDEN;
+ }
+
+ register_timeout ("send", r);
+ send_http_header (r);
+
+ if (!r->header_only) send_fd (f, r);
+ pfclose (r->pool, f);
+ return OK;
+}
+
+
+Finally, if all of this is too much of a challenge, there are a few
+ways out of it. First off, as shown above, a response handler which
+has not yet produced any output can simply return an error code, in
+which case the server will automatically produce an error response.
+Secondly, it can punt to some other handler by invoking
+internal_redirect, which is how the internal redirection
+machinery discussed above is invoked. A response handler which has
+internally redirected should always return OK.
+
+(Invoking internal_redirect from handlers which are
+not response handlers will lead to serious confusion).
+
+
+
+Stuff that should be discussed here in detail:
+
+
+ - Authentication-phase handlers not invoked unless auth is
+ configured for the directory.
+
- Common auth configuration stored in the core per-dir
+ configuration; it has accessors
auth_type,
+ auth_name, and requires.
+ - Common routines, to handle the protocol end of things, at least
+ for HTTP basic authentication (
get_basic_auth_pw,
+ which sets the connection->user structure field
+ automatically, and note_basic_auth_failure, which
+ arranges for the proper WWW-Authenticate: header
+ to be sent back).
+
+
+
+
+When a request has internally redirected, there is the question of
+what to log. Apache handles this by bundling the entire chain of
+redirects into a list of request_rec structures which are
+threaded through the r->prev and r->next
+pointers. The request_rec which is passed to the logging
+handlers in such cases is the one which was originally built for the
+intial request from the client; note that the bytes_sent field will
+only be correct in the last request in the chain (the one for which a
+response was actually sent).
+
+
+
+One of the problems of writing and designing a server-pool server is
+that of preventing leakage, that is, allocating resources (memory,
+open files, etc.), without subsequently releasing them. The resource
+pool machinery is designed to make it easy to prevent this from
+happening, by allowing resource to be allocated in such a way that
+they are automatically released when the server is done with
+them.
+
+The way this works is as follows: the memory which is allocated, file
+opened, etc., to deal with a particular request are tied to a
+resource pool which is allocated for the request. The pool
+is a data structure which itself tracks the resources in question.
+
+When the request has been processed, the pool is cleared. At
+that point, all the memory associated with it is released for reuse,
+all files associated with it are closed, and any other clean-up
+functions which are associated with the pool are run. When this is
+over, we can be confident that all the resource tied to the pool have
+been released, and that none of them have leaked.
+
+Server restarts, and allocation of memory and resources for per-server
+configuration, are handled in a similar way. There is a
+configuration pool, which keeps track of resources which were
+allocated while reading the server configuration files, and handling
+the commands therein (for instance, the memory that was allocated for
+per-server module configuration, log files and other files that were
+opened, and so forth). When the server restarts, and has to reread
+the configuration files, the configuration pool is cleared, and so the
+memory and file descriptors which were taken up by reading them the
+last time are made available for reuse.
+
+It should be noted that use of the pool machinery isn't generally
+obligatory, except for situations like logging handlers, where you
+really need to register cleanups to make sure that the log file gets
+closed when the server restarts (this is most easily done by using the
+function pfopen, which also
+arranges for the underlying file descriptor to be closed before any
+child processes, such as for CGI scripts, are execed), or
+in case you are using the timeout machinery (which isn't yet even
+documented here). However, there are two benefits to using it:
+resources allocated to a pool never leak (even if you allocate a
+scratch string, and just forget about it); also, for memory
+allocation, palloc is generally faster than
+malloc.
+
+We begin here by describing how memory is allocated to pools, and then
+discuss how other resources are tracked by the resource pool
+machinery.
+
+
Allocation of memory in pools
+
+Memory is allocated to pools by calling the function
+palloc, which takes two arguments, one being a pointer to
+a resource pool structure, and the other being the amount of memory to
+allocate (in chars). Within handlers for handling
+requests, the most common way of getting a resource pool structure is
+by looking at the pool slot of the relevant
+request_rec; hence the repeated appearance of the
+following idiom in module code:
+
+
+int my_handler(request_rec *r)
+{
+ struct my_structure *foo;
+ ...
+
+ foo = (foo *)palloc (r->pool, sizeof(my_structure));
+}
+
+
+Note that there is no pfree ---
+palloced memory is freed only when the associated
+resource pool is cleared. This means that palloc doesn't
+have to do as much accounting as malloc(); all it does in
+the typical case is to round up the size, bump a pointer, and do a
+range check.
+
+(It also raises the possibility that heavy use of palloc
+could cause a server process to grow excessively large. There are
+two ways to deal with this, which are dealt with below; briefly, you
+can use malloc, and try to be sure that all of the memory
+gets explicitly freed, or you can allocate a sub-pool of
+the main pool, allocate your memory in the sub-pool, and clear it out
+periodically. The latter technique is discussed in the section on
+sub-pools below, and is used in the directory-indexing code, in order
+to avoid excessive storage allocation when listing directories with
+thousands of files).
+
+
Allocating initialized memory
+
+There are functions which allocate initialized memory, and are
+frequently useful. The function pcalloc has the same
+interface as palloc, but clears out the memory it
+allocates before it returns it. The function pstrdup
+takes a resource pool and a char * as arguments, and
+allocates memory for a copy of the string the pointer points to,
+returning a pointer to the copy. Finally pstrcat is a
+varargs-style function, which takes a pointer to a resource pool, and
+at least two char * arguments, the last of which must be
+NULL. It allocates enough memory to fit copies of each
+of the strings, as a unit; for instance:
+
+
+ pstrcat (r->pool, "foo", "/", "bar", NULL);
+
+
+returns a pointer to 8 bytes worth of memory, initialized to
+"foo/bar".
+
+Tracking open files, etc.
+
+As indicated above, resource pools are also used to track other sorts
+of resources besides memory. The most common are open files. The
+routine which is typically used for this is pfopen, which
+takes a resource pool and two strings as arguments; the strings are
+the same as the typical arguments to fopen, e.g.,
+
+
+ ...
+ FILE *f = pfopen (r->pool, r->filename, "r");
+
+ if (f == NULL) { ... } else { ... }
+
+
+There is also a popenf routine, which parallels the
+lower-level open system call. Both of these routines
+arrange for the file to be closed when the resource pool in question
+is cleared.
+
+Unlike the case for memory, there are functions to close
+files allocated with pfopen, and popenf,
+namely pfclose and pclosef. (This is
+because, on many systems, the number of files which a single process
+can have open is quite limited). It is important to use these
+functions to close files allocated with pfopen and
+popenf, since to do otherwise could cause fatal errors on
+systems such as Linux, which react badly if the same
+FILE* is closed more than once.
+
+(Using the close functions is not mandatory, since the
+file will eventually be closed regardless, but you should consider it
+in cases where your module is opening, or could open, a lot of files).
+
+
Other sorts of resources --- cleanup functions
+
+More text goes here. Describe the the cleanup primitives in terms of
+which the file stuff is implemented; also, spawn_process.
+
+Fine control --- creating and dealing with sub-pools, with a note
+on sub-requests
+
+On rare occasions, too-free use of palloc() and the
+associated primitives may result in undesirably profligate resource
+allocation. You can deal with such a case by creating a
+sub-pool, allocating within the sub-pool rather than the main
+pool, and clearing or destroying the sub-pool, which releases the
+resources which were associated with it. (This really is a
+rare situation; the only case in which it comes up in the standard
+module set is in case of listing directories, and then only with
+very large directories. Unnecessary use of the primitives
+dicussed here can hair up your code quite a bit, with very little
+gain).
+
+The primitive for creating a sub-pool is make_sub_pool,
+which takes another pool (the parent pool) as an argument. When the
+main pool is cleared, the sub-pool will be destroyed. The sub-pool
+may also be cleared or destroyed at any time, by calling the functions
+clear_pool and destroy_pool, respectively.
+(The difference is that clear_pool frees resources
+associated with the pool, while destroy_pool also
+deallocates the pool itself. In the former case, you can allocate new
+resources within the pool, and clear it again, and so forth; in the
+latter case, it is simply gone).
+
+One final note --- sub-requests have their own resource pools, which
+are sub-pools of the resource pool for the main request. The polite
+way to reclaim the resources associated with a sub request which you
+have allocated (using the sub_req_lookup_... functions)
+is destroy_sub_request, which frees the resource pool.
+Before calling this function, be sure to copy anything that you care
+about which might be allocated in the sub-request's resource pool into
+someplace a little less volatile (for instance, the filename in its
+request_rec structure).
+
+(Again, under most circumstances, you shouldn't feel obliged to call
+this function; only 2K of memory or so are allocated for a typical sub
+request, and it will be freed anyway when the main request pool is
+cleared. It is only when you are allocating many, many sub-requests
+for a single main request that you should seriously consider the
+destroy... functions).
+
+
+
+One of the design goals for this server was to maintain external
+compatibility with the NCSA 1.3 server --- that is, to read the same
+configuration files, to process all the directives therein correctly,
+and in general to be a drop-in replacement for NCSA. On the other
+hand, another design goal was to move as much of the server's
+functionality into modules which have as little as possible to do with
+the monolithic server core. The only way to reconcile these goals is
+to move the handling of most commands from the central server into the
+modules.
+
+However, just giving the modules command tables is not enough to
+divorce them completely from the server core. The server has to
+remember the commands in order to act on them later. That involves
+maintaining data which is private to the modules, and which can be
+either per-server, or per-directory. Most things are per-directory,
+including in particular access control and authorization information,
+but also information on how to determine file types from suffixes,
+which can be modified by AddType and
+DefaultType directives, and so forth. In general, the
+governing philosophy is that anything which can be made
+configurable by directory should be; per-server information is
+generally used in the standard set of modules for information like
+Aliases and Redirects which come into play
+before the request is tied to a particular place in the underlying
+file system.
+
+Another requirement for emulating the NCSA server is being able to
+handle the per-directory configuration files, generally called
+.htaccess files, though even in the NCSA server they can
+contain directives which have nothing at all to do with access
+control. Accordingly, after URI -> filename translation, but before
+performing any other phase, the server walks down the directory
+hierarchy of the underlying filesystem, following the translated
+pathname, to read any .htaccess files which might be
+present. The information which is read in then has to be
+merged with the applicable information from the server's own
+config files (either from the <Directory> sections
+in access.conf, or from defaults in
+srm.conf, which actually behaves for most purposes almost
+exactly like <Directory />).
+
+Finally, after having served a request which involved reading
+.htaccess files, we need to discard the storage allocated
+for handling them. That is solved the same way it is solved wherever
+else similar problems come up, by tying those structures to the
+per-transaction resource pool.
+
+
+
+Let's look out how all of this plays out in mod_mime.c,
+which defines the file typing handler which emulates the NCSA server's
+behavior of determining file types from suffixes. What we'll be
+looking at, here, is the code which implements the
+AddType and AddEncoding commands. These
+commands can appear in .htaccess files, so they must be
+handled in the module's private per-directory data, which in fact,
+consists of two separate tables for MIME types and
+encoding information, and is declared as follows:
+
+
+typedef struct {
+ table *forced_types; /* Additional AddTyped stuff */
+ table *encoding_types; /* Added with AddEncoding... */
+} mime_dir_config;
+
+
+When the server is reading a configuration file, or
+<Directory> section, which includes one of the MIME
+module's commands, it needs to create a mime_dir_config
+structure, so those commands have something to act on. It does this
+by invoking the function it finds in the module's "create per-dir
+config slot", with two arguments: the name of the directory to which
+this configuration information applies (or NULL for
+srm.conf), and a pointer to a resource pool in which the
+allocation should happen.
+
+(If we are reading a .htaccess file, that resource pool
+is the per-request resource pool for the request; otherwise it is a
+resource pool which is used for configuration data, and cleared on
+restarts. Either way, it is important for the structure being created
+to vanish when the pool is cleared, by registering a cleanup on the
+pool if necessary).
+
+For the MIME module, the per-dir config creation function just
+pallocs the structure above, and a creates a couple of
+tables to fill it. That looks like this:
+
+
+void *create_mime_dir_config (pool *p, char *dummy)
+{
+ mime_dir_config *new =
+ (mime_dir_config *) palloc (p, sizeof(mime_dir_config));
+
+ new->forced_types = make_table (p, 4);
+ new->encoding_types = make_table (p, 4);
+
+ return new;
+}
+
+
+Now, suppose we've just read in a .htaccess file. We
+already have the per-directory configuration structure for the next
+directory up in the hierarchy. If the .htaccess file we
+just read in didn't have any AddType or
+AddEncoding commands, its per-directory config structure
+for the MIME module is still valid, and we can just use it.
+Otherwise, we need to merge the two structures somehow.
+
+To do that, the server invokes the module's per-directory config merge
+function, if one is present. That function takes three arguments:
+the two structures being merged, and a resource pool in which to
+allocate the result. For the MIME module, all that needs to be done
+is overlay the tables from the new per-directory config structure with
+those from the parent:
+
+
+void *merge_mime_dir_configs (pool *p, void *parent_dirv, void *subdirv)
+{
+ mime_dir_config *parent_dir = (mime_dir_config *)parent_dirv;
+ mime_dir_config *subdir = (mime_dir_config *)subdirv;
+ mime_dir_config *new =
+ (mime_dir_config *)palloc (p, sizeof(mime_dir_config));
+
+ new->forced_types = overlay_tables (p, subdir->forced_types,
+ parent_dir->forced_types);
+ new->encoding_types = overlay_tables (p, subdir->encoding_types,
+ parent_dir->encoding_types);
+
+ return new;
+}
+
+
+As a note --- if there is no per-directory merge function present, the
+server will just use the subdirectory's configuration info, and ignore
+the parent's. For some modules, that works just fine (e.g., for the
+includes module, whose per-directory configuration information
+consists solely of the state of the XBITHACK), and for
+those modules, you can just not declare one, and leave the
+corresponding structure slot in the module itself NULL.
+
+
+
+Now that we have these structures, we need to be able to figure out
+how to fill them. That involves processing the actual
+AddType and AddEncoding commands. To find
+commands, the server looks in the module's command table.
+That table contains information on how many arguments the commands
+take, and in what formats, where it is permitted, and so forth. That
+information is sufficient to allow the server to invoke most
+command-handling functions with preparsed arguments. Without further
+ado, let's look at the AddType command handler, which
+looks like this (the AddEncoding command looks basically
+the same, and won't be shown here):
+
+
+char *add_type(cmd_parms *cmd, mime_dir_config *m, char *ct, char *ext)
+{
+ if (*ext == '.') ++ext;
+ table_set (m->forced_types, ext, ct);
+ return NULL;
+}
+
+
+This command handler is unusually simple. As you can see, it takes
+four arguments, two of which are preparsed arguments, the third being
+the per-directory configuration structure for the module in question,
+and the fourth being a pointer to a cmd_parms structure.
+That structure contains a bunch of arguments which are frequently of
+use to some, but not all, commands, including a resource pool (from
+which memory can be allocated, and to which cleanups should be tied),
+and the (virtual) server being configured, from which the module's
+per-server configuration data can be obtained if required.
+
+Another way in which this particular command handler is unusually
+simple is that there are no error conditions which it can encounter.
+If there were, it could return an error message instead of
+NULL; this causes an error to be printed out on the
+server's stderr, followed by a quick exit, if it is in
+the main config files; for a .htaccess file, the syntax
+error is logged in the server error log (along with an indication of
+where it came from), and the request is bounced with a server error
+response (HTTP error status, code 500).
+
+The MIME module's command table has entries for these commands, which
+look like this:
+
+
+command_rec mime_cmds[] = {
+{ "AddType", add_type, NULL, OR_FILEINFO, TAKE2,
+ "a mime type followed by a file extension" },
+{ "AddEncoding", add_encoding, NULL, OR_FILEINFO, TAKE2,
+ "an encoding (e.g., gzip), followed by a file extension" },
+{ NULL }
+};
+
+
+The entries in these tables are:
+
+
+ - The name of the command
+
- The function which handles it
+
- a
(void *) pointer, which is passed in the
+ cmd_parms structure to the command handler ---
+ this is useful in case many similar commands are handled by the
+ same function.
+ - A bit mask indicating where the command may appear. There are
+ mask bits corresponding to each
AllowOverride
+ option, and an additional mask bit, RSRC_CONF,
+ indicating that the command may appear in the server's own
+ config files, but not in any .htaccess
+ file.
+ - A flag indicating how many arguments the command handler wants
+ preparsed, and how they should be passed in.
+
TAKE2 indicates two preparsed arguments. Other
+ options are TAKE1, which indicates one preparsed
+ argument, FLAG, which indicates that the argument
+ should be On or Off, and is passed in
+ as a boolean flag, RAW_ARGS, which causes the
+ server to give the command the raw, unparsed arguments
+ (everything but the command name itself). There is also
+ ITERATE, which means that the handler looks the
+ same as TAKE1, but that if multiple arguments are
+ present, it should be called multiple times, and finally
+ ITERATE2, which indicates that the command handler
+ looks like a TAKE2, but if more arguments are
+ present, then it should be called multiple times, holding the
+ first argument constant.
+ - Finally, we have a string which describes the arguments that
+ should be present. If the arguments in the actual config file
+ are not as required, this string will be used to help give a
+ more specific error message. (You can safely leave this
+
NULL).
+
+
+Finally, having set this all up, we have to use it. This is
+ultimately done in the module's handlers, specifically for its
+file-typing handler, which looks more or less like this; note that the
+per-directory configuration structure is extracted from the
+request_rec's per-directory configuration vector by using
+the get_module_config function.
+
+
+int find_ct(request_rec *r)
+{
+ int i;
+ char *fn = pstrdup (r->pool, r->filename);
+ mime_dir_config *conf =
+ (mime_dir_config *)get_module_config(r->per_dir_config, &mime_module);
+ char *type;
+
+ if (S_ISDIR(r->finfo.st_mode)) {
+ r->content_type = DIR_MAGIC_TYPE;
+ return OK;
+ }
+
+ if((i=rind(fn,'.')) < 0) return DECLINED;
+ ++i;
+
+ if ((type = table_get (conf->encoding_types, &fn[i])))
+ {
+ r->content_encoding = type;
+
+ /* go back to previous extension to try to use it as a type */
+
+ fn[i-1] = '\0';
+ if((i=rind(fn,'.')) < 0) return OK;
+ ++i;
+ }
+
+ if ((type = table_get (conf->forced_types, &fn[i])))
+ {
+ r->content_type = type;
+ }
+
+ return OK;
+}
+
+
+
+
+
+The basic ideas behind per-server module configuration are basically
+the same as those for per-directory configuration; there is a creation
+function and a merge function, the latter being invoked where a
+virtual server has partially overriden the base server configuration,
+and a combined structure must be computed. (As with per-directory
+configuration, the default if no merge function is specified, and a
+module is configured in some virtual server, is that the base
+configuration is simply ignored).
+
+The only substantial difference is that when a command needs to
+configure the per-server private module data, it needs to go to the
+cmd_parms data to get at it. Here's an example, from the
+alias module, which also indicates how a syntax error can be returned
+(note that the per-directory configuration argument to the command
+handler is declared as a dummy, since the module doesn't actually have
+per-directory config data):
+
+
+char *add_redirect(cmd_parms *cmd, void *dummy, char *f, char *url)
+{
+ server_rec *s = cmd->server;
+ alias_server_conf *conf =
+ (alias_server_conf *)get_module_config(s->module_config,&alias_module);
+ alias_entry *new = push_array (conf->redirects);
+
+ if (!is_url (url)) return "Redirect to non-URL";
+
+ new->fake = f; new->real = url;
+ return NULL;
+}

+ *) Add HAVE_MMAP to SCO 5. [Ben Laurie]
+
+ *) SCO 5 reportedly (by Jay Thorne <jay@result.com>) requires
+ FCNTL_SERIALIZED_ACCEPT. Added to conf.h. [Ben Laurie]
+
+ *) Clear up some nasty (int)NULLs. [Ben Laurie]
+
+ *) Clean code to warning level 3 under SCO 5. [Ben Laurie]
+
+ *) Fix potential buffer overrun in mod_proxy.c. [Ben Laurie]
+
+ *) Internal redirects now preserve HTTP headers [Rob Hartil]
+
+ *) Adds SysV-based Shared Memory support for Apache [Jim Jagielski]
+
+ *) Use bread() etc instead of fread() for reading/writing to client.
+ Move the count of bytes sent into the buffering routines.
+ Rewrite the buffering routines to provide bputc(), bgetc() macros.
+ [David Robinson]
+
+ *) Make hostname_lookups a per-directory core configuration variable.
+ Replace all accesses to the connection.remote_host and remote_name
+ variables to calls to get_remote_host(), which is now in http_core.c.
+ [David Robinson]
+
+ *) Make do_rfc1413 a per-directory core configuration variable.
+ Replace all accesses to the connection.remote_logname
+ variables to calls to get_remote_logname(). Rewrite rfc931.c as
+ rfc1413.c to conform to new standard, avoid stdio and avoid syslog.
+ [David Robinson]
+
+ *) CGI variables are now available to server side include directives
+ as well as the QUERY_STRING_UNESCAPED variable, as required by
+ the NCSA server side include documentation. [Nathan Schrenk]
+
+ *) Better diagnostic info to enhance "malformed header from script"
+ [Rob Hartill]
+
+ *) Improvements and new features added to the UserDir directive:
+ Additional forms of specifiying user directories, and the ability to
+ specify multiple user directories, much like the DirectoryIndex
+ command. [Alexei Kosut]
+
+ *) Internal redirects no longer force the GET method, except when desired
+ (CGI scripts and error documents). [Adam Sussman and Rasmus Lerdorf]
+
+ *) Rewrite/reorganization of mod_imap.c. New handling of default, base
+ and relative URLs. New Configuration directives. Support for creating
+ non-graphical menu added. (backwards compatible). [Nathan Kurz]
+
+ *) New module which allows Apache's CGI and SSI environment to inherit
+ environment variables from the shell which invoked the httpd
+ process. CERN webservers are able to do this, so this module is
+ especially useful to webadmins who wish to migrate from CERN to Apache
+ without rewriting all their scripts [Andrew Wilson]
+
+ *) Updated /cgi-src to the latest NCSA version, including the IBM-ERS patch
+ to close a security hole, as well as other changes to the distribution
+ since it was last updated (Apache 0.8.5) [Alexei Kosut]
+
+ *) Move Configuration to Configuration.tmpl for CVS development. Make CVS
+ ignore Configuration, Makefile and modules.c. [Ben Laurie]
+
+Changes with Apache 1.1b0
+
+ *) Use shmget() (and family) for shared memory for the scoreboard
+ for SysV-based systems; basically A/UX and IRIX. Allow for
+ memory break-point (brk(0)) to be moved if need be before
+ attaching the mem segment. [Jim Jagielski]
+
+ *) Use mmap() to allocated shared memory for the scoreboard on
+ Solaris, SunOS, Digital UNIX, BSDI and HP/UX. It should work on
+ most of the other architectures. [David Robinson]
+
+ *) Cache the contents of .htaccess file for the duration of a request.
+ [David Robinson]
+
+ *) Avoid use of strftime() whilst processing request. [David Robinson]
+
+ *) Add the ability to have media type-based CGI script actions,
+ as well as an example and relevent srm.conf entries. [Alexei Kosut]
+
+ *) Update to the icon set, and apache_pb (Powered by Apache!) logo
+ added [Alexei Kosut]
+
+ *) Added an extra variable for use in mod_include: FILE_OWNER
+ which contains the owner of the file. [Nick Williams]
+
+ *) Adds support for Keep-Alive persistent connections, as defined
+ in the HTTP/1.1 draft and implemented by several existing browsers
+ and servers. [Alexei Kosut and Rob Hartill]
+
+ *) "HostnameLookups" is a new httpd.conf setting (on/off) to make obsolete
+ -DMINIMAL_DNS and enable name lookups to be switched
+ on/off without recompiling Apache. [Rob Hartill]
+
+ *) Allows Redirect entries in .htaccess files, allowing users to
+ add their own redirects without using CGI scripts, asis files, or
+ access to the main server conf file. [Alexei Kosut]
+
+ *) Scoreboard monitor program (C version) in support/ directory
+ [Jim Jagielski]
+
+ *) A module to implement a caching HTTP and FTP proxy server
+ [David Robinson]
+
+ *) Adds OS/2 support [Garey Smiley]
+
+ *) Add Listen directive, causing Apache to bind to the address and
+ port specified. Allow <VirtualHost *>, <VirtualHost *:port>,
+ VirtualHost addr:*> syntaxes [David Robinson]
+
+ *) Allow anonymous HTTP logins [Dirk van Gulik]
+
+ *) Authentication using Berkeley DB [Andrew Cohen]
+
+ *) Authentication using mSQL [Dirk van Gulik]
+
+ *) Emulate the CERN HTTPD metafile semantics, allowing the ability
+ to manipulate HTTP headers for individual files. [Andrew Wilson[
+
+Changes with Apache 1.0.3
+
+ *) Internal redirects which occur in mod_dir.c now preserve the
+ query portion of a request (the bit after the question mark).
+ [Adam Sussman]
+
+ *) Escape active characters '<', '>' and '&' in html output in
+ directory listings, error messages and redirection links.
+ [David Robinson]
+
+ *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
+
+ *) Fix for POSIX compliance in waiting for processes in alloc.c.
+ [Nick Williams]
+
+ *) setsockopt no longer takes a const declared argument [Martijn Koster]
+
+ *) Reset timeout timer after each successful fwrite() to the network.
+ This patch adds a reset_timeout() procedure that is called by
+ send_fd() to reset the timeout ever time data is written to the net.
+ [Nathan Schrenk]
+
+ *) timeout() signal handler now checks for SIGPIPE and reports
+ lost connections in a more user friendly way. [Rob Hartill]
+
+ *) Location of the "scoreboard" file which used to live in /tmp is
+ now configurable (for OSes that can't use mmap) via ScoreBoardFile
+ which works similar to PidFile (in httpd.conf) [Rob Hartill]
+
+ *) Include sys/resource.h in the correct place for SunOS4 [Samerr Parekh]
+
+ *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
+ which caused a SEGV with cookies enabled
+
+ *) Output warning when MinSpareServers is set to <= 0 and change it to 1
+ [Rob Hartill]
+
+ *) Log the UNIX textual error returned by some system calls, in
+ particular errors from accept() [David Robinson]
+
+ *) Add strerror function to util.c for SunOS4 [Randy Terbush]
+
+Changes with Apache 1.0.2
+
+ *) patch to get Apache compiled on UnixWare 2.x, recommended as
+ a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
+
+ *) Fix get_basic_auth_pw() to set the auth_type of the request.
+ [David Robinson]
+
+ *) past changes to http_config.c to only use the
+ setrlimit function on systems defining RLIMIT_NOFILE
+ broke the feature on SUNOS4. Now defines HAVE_RESOURCE
+ for SUNOS and prototypes the needed functions.
+
+ *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
+ [David Robinson]
+
+ *) Fix use of pointer to scratch memory. [Cliff Skolnick]
+
+ *) Merge multiple headers from CGI scripts instead of taking last
+ one. [David Robinson]
+
+ *) Add support for SCO 5. [Ben Laurie]
+
+Changes with Apache 1.0.1
+
+ *) Silence mod_log_referer and mod_log_agent if not configured
+ [Randy Terbush]
+
+ *) Recursive includes can occur if the client supplies PATH_INFO data
+ and the server provider uses relative links; as file.html
+ relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
+
+ *) The replacement for initgroups() did not call {set,end}grent(). This
+ had two implications: if anything else used getgrent(), then
+ initgroups() would fail, and it was consuming a file descriptor.
+ [Ben Laurie]
+
+ *) On heavily loaded servers it was possible for the scoreboard to get
+ out of sync with reality, as a result of a race condition.
+ The observed symptoms are far more Apaches running than should
+ be, and heavy system loads, generally followed by catastrophic
+ system failure. [Ben Laurie]
+
+ *) Fix typo in licence. [David Robinson]
+
+Changes with Apache 1.0.0
+
+ *) 'dbmmanage' script now takes fourth command-line argument, which is
+ group(s) of the user, if given. [Rob Hartill]
+
+ *) httpd_monitor Perl utility script added to "support" directory;
+ lets you know what your active server processes are up to. [Known
+ to work on SunOS and HP-UX at least]. [Rob Hartill]
+
+ *) Passes TZ environment variable to child processes if set on startup
+ [ David Robinson ]
+
+ *) Attempting to retrieve the URI /foo/bar/zot.map (an imagemap request
+ with *no* QUERY_STRING) returns the default URL, rather than a core
+ dump. [Mark Cox]
+
+ *) Attempting to configure auth without any "requires" lines should now
+ be equivalent to "require valid-user", rather than a core dump.
+ [Patch supplied by J. Katzman]
+
+ *) Getparents() routine fixed to handle some awkward corner cases better;
+ in particular, '/./' is eliminated from incoming URIs. Also fixed the
+ no2slash() utility routine to reduce any number of consecutive slashes
+ to one. These changes keep "trick" URIs from avoiding <Directory>
+ checks. [David Robinson]
+
+ *) Allowed any number of '/' characters to match a single '/' when
+ checking for Aliases; this keeps certain ScriptAlias directives
+ from getting bypassed. [Robert Thau]
+
+ *) DBM group code now checks all groups, not just the first [Rob Hartill]
+
+ *) "allow from good.com" no longer allows clients from nogood.com to
+ connect; formerly this was allowed because the terminal substrings
+ do match. [Robert Thau]
+
+ *) Transactions interrupted in the middle of processing some include
+ directive are now logged correctly [Robert Thau]
+
+ *) Cleaned up Configure script so it doesn't abuse EXTRA_LIBS to specify
+ host-specific default libraries. [Ben Laurie]
+
+ *) Cleaned up http_main code a bit; IdentityCheck may now work better on
+ systems with virtual hosts. [David Robinson]
+
+ *) Improved installation instructions in top-level README [Brian Behlendorf]
+
+Changes with Apache 0.8.16
+
+ *) New man page for 'httpd' added to support directory [David Robinson]
+
+ *) .htgroup files can have more than one line giving members for a
+ given group (each must have the group name in front), for NCSA
+ back-compatibility [Robert Thau]
+
+ *) Mutual exclusion around accept() is on by default for SVR4 systems
+ generally, since they generally can't handle multiple processes in
+ accept() on the same socket. This should cure flaky behavior on
+ a lot of those systems. [David Robinson]
+
+ *) AddType, AddEncoding, and AddLanguage directives take multiple
+ extensions on a single command line [David Robinson]
+
+ *) UserDir can be disabled for a given virtual host by saying
+ "UserDir disabled" in the <VirtualHost> section --- it was a bug
+ that this didn't work. [David Robinson]
+
+ *) Compiles on QNX [Ben Laurie]
+
+ *) Corrected parsing of ctime time format [David Robinson]
+
+ *) httpd does a perror() before exiting if it can't log its pid
+ to the PidFile, to make diagnosing the error a bit easier.
+ [David Robinson]
+
+ *) <!--#include file="..."--> can no longer include files in the
+ parent directory, for NCSA back-compatibility. [David Robinson]
+
+ *) '~' is *not* escaped in URIs generated for directory listings
+ [Roy Fielding]
+
+ *) Eliminated compiler warning in the imagemap module [Randy Terbush]
+
+ *) Fixed bug involving handling URIs with escaped %-characters
+ in redirects [David Robinson]
+
+Changes with Apache 0.8.15
+
+ *) Switched to new, simpler license
+
+ *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
+
+ *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
+
+ *) Reject paths containing %-escaped '%' or null characters [David Robinson]
+
+ *) Correctly handles internal redirects to files with names containing '%'
+ [David Robinson]
+
+ *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
+
+ *) Use geteuid() rather than getuid() to see if we have root privilege,
+ so that server correctly resets privilege if run setuid root. [Andrew
+ Wilson]
+
+ *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
+ [Randy Terbush]
+
+ *) Fix relative URLs in imagemap files [Randy Terbush]
+
+ *) Somewhat better fix for the old "Alias /foo/ /bar/" business
+ [David Robinson]
+
+ *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
+ entries all name the same one. [David Robinson]
+
+ *) Fix directory listings with filenames containing unusual characters
+ [David Robinson]
+
+ *) Better URI-escaping for generated URIs in directories with filenames
+ containing unusual characters [Ben Laurie]
+
+ *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
+
+ *) Unblock alarms on error return from spawn_child() [David Robinson]
+
+ *) Sample Config files have extra note for SCO users [Ben Laurie]
+
+ *) Configuration has note for HP-UX users [Rob Hartill]
+
+ *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
+
+ *) Nuked bogus #define in httpd.h [David Robinson]
+
+ *) Better test for whether a system has setrlimit() [David Robinson]
+
+ *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
+
+ *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
+ [Ben Laurie]
+
+Changes with Apache 0.8.14
+
+ *) Compiles on SCO ODT 3.0 [Ben Laurie]
+
+ *) AddDescription works (better) [Ben Laurie]
+
+ *) Leaves an intelligible error diagnostic when it can't set group
+ privileges on standalone startup [Andrew Wilson]
+
+ *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
+ that machine, which claims to be BSD but does not support RLIMIT.
+ [Randy Terbush]
+
+ *) gcc -Wall no longer complains about an unused variable when util.c
+ is compiled with -DMINIMAL_DNS [Andrew Wilson]
+
+ *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
+
+Changes with Apache 0.8.13
+
+ *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
+
+ *) Have built-in imagemap code recognize & honor Point directive [James
+ Cloos]
+
+ *) Generate cleaner directory listings in directories with a mix of
+ long and short filenames [Rob Hartill]
+
+ *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
+
+ *) Properly default ServerName for virtual servers [Robert Thau]
+
+ *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
+ Paul Richards and a cast of thousands...]
+
+ *) On self-identified BSD systems (we don't try to guess any more),
+ allocate a few extra file descriptors per virtual host with setrlimit,
+ if we can, to avoid running out. [Randy Terbush]
+
+ *) Write 22-character lock file name into buffer with enough space
+ on startup [Konstantin Olchanski]
+
+ *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
+ Pinkerton]
+
+ *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
+
+ *) Suppress -Wall warning by initializing variable in negotation code
+ [Tobias Weingartner]
+
+Changes with Apache 0.8.12
+
+ *) Doesn't pause three seconds after including a CGI script which is
+ too slow to die off (this is done by not even trying to kill off
+ subprocesses, including the SIGTERM/pause/SIGKILL routine, until
+ after the entire document has been processed). [Robert Thau]
+
+ *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
+
+ *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
+
+ *) Allows .htaccess files to override <Directory> sections naming the
+ same directory [David Robinson]
+
+ *) Removed an efficiency hack in sub_req_lookup_uri which was
+ causing certain extremely marginal cases (e.g., ScriptAlias of a
+ *particular* index.html file) to fail. [David Robinson]
+
+ *) Doesn't log an error when the requested URI requires
+ authentication, but no auth header line was supplied by the
+ client; this is a normal condition (the client doesn't no auth is
+ needed here yet). [Robert Thau]
+
+ *) Behaves more sanely when the name server loses its mind [Sean Welch]
+
+ *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
+
+ *) RFC931 code no longer passes out name of prior clients on current
+ requests if the current request came from a server that doesn't
+ do RFC931. [David Robinson]
+
+ *) Configuration script accepts "Module" lines with trailing whitespace.
+ [Robert Thau]
+
+ *) Cleaned up compiler warning from mod_access.c [Robert Thau]
+
+ *) Cleaned up comments in mod_cgi.c [Robert Thau]
+
+Changes with Apache 0.8.11
+
+ *) Wildcard <Directory> specifications work. [Robert Thau]
+
+ *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
+
+ *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
+ the file being requested itself, in addition to the directories leading
+ up to it. [Robert Thau]
+
+ *) Logs access failures due to symlink checks or invalid client address
+ in the error log [Roy Fielding, Robert Thau]
+
+ *) Symlink checks deal correctly with systems where lstat of
+ "/path/to/some/link/" follows the link. [Thau, Fielding]
+
+ *) Doesn't reset DirectoryIndex to 'index.html' when
+ other directory options are set in a .htaccess file. [Robert Thau]
+
+ *) Clarifed init code and nuked bogus warning in mod_access.c
+ [Florent Guillaume]
+
+ *) Corrected several directives in sample srm.conf
+ --- includes corrections to directory indexing icon-related directives
+ (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
+ icons for encodings right, and turning on AddEncoding by default).
+ [Roy Fielding]
+
+ *) Corrected descriptions of args to AddIcon and AddAlt in command table
+ [James Cloos]
+
+ *) INSTALL & README mention "contributed modules" directory [Brian
+ Behlendorf]
+
+ *) Fixed English in the license language... "for for" --> "for".
+ [Roy Fielding]
+
+ *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
+ mod_alias.c, merging it almost completely with handling of Alias, and
+ adding a 'notes' field to the request_rec which allows the CGI module
+ to discover whether the Alias module has put this request through
+ ScriptAlias (which it needs to know for back-combatibility, as the old
+ NCSA code did not check Options ExecCGI in ScriptAliased directories).
+ [Robert Thau]
+
+
+Changes with Apache 0.8.10
+
+ *) AllowOverride applies to the named directory, and not just
+ subdirectories. [David Robinson]
+
+ *) Do locking for accept() exclusion (on systems that need it)
+ using a special file created for the purpose in /usr/tmp, and
+ not the error log; using the error log causes real problems
+ if it's NFS-mounted; this is known to be the cause of a whole
+ lot of "server hang" problems with Solaris. [David Robinson;
+ thanks to Merten Schumann for help diagnosing the problem].
+
+Changes with Apache 0.8.9
+
+ *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
+
+ *) Nested includes see environment variables of the including document,
+ for NCSA bug-compatibility (some sites have standard footer includes
+ which try to print out the last-modified date). [Eric Hagberg/Robert
+ Thau]
+
+ *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
+ URI as a CGI script, even if it would have been treated as something
+ else if requested directly, for NCSA back-combatibility. (Note that
+ this means that people who know the name of the script can see the
+ code just by asking for it). [Robert Thau]
+
+ *) New version of dbmmanage script included in support directory as
+ dbmmanage.new.
+
+ *) Check if scoreboard file couldn't be opened, and say so, rather
+ then going insane [David Robinson]
+
+ *) POST to CGI works on A/UX [Jim Jaglieski]
+
+ *) AddIcon and AddAlt commands work properly [Rob Hartill]
+
+ *) NCSA server push works properly --- the Arena bug compatibility
+ workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
+ if you still want the workaround). [Rob Hartill]
+
+ *) If client didn't submit any Accept-encodings, ignore encodings in
+ content negotiation. (NB this will all have to be reworked anyway
+ for the new HTTP draft). [Florent Guillaume]
+
+ *) Don't dump core when trying to log timed-out requests [Jim Jaglieski]
+
+ *) Really honor CacheNegotiatedDocs [Florent Guillaume]
+
+ *) Give Redirect priority over Alias, for NCSA bug compatibility
+ [David Robinson]
+
+ *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
+ paralleling earlier bug fix for CGI [David Robinson]
+
+ *) If DBM auth is improperly configured, report a server error and don't
+ dump core.
+
+ *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
+ it seems to work well enough without it (even in a 10 hits/sec
+ workout), and the overhead for the locking under A/UX is
+ alarmingly high (though it is very low on other systems).
+ [Eric Hagberg]
+
+ *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
+
+ *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
+ Behlendorf/Eric Hagberg]
+
+ *) More improvements to default Configuration for A/UX [Jim Jaglieski]
+
+ *) Compiles clean on NEXT [Rob Hartill]
+
+ *) Compiles clean on SGI [Robert Thau]
+
+Changes with Apache 0.8.8
+
+ *) SunOS library prototypes now never included unless explicitly
+ requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
+ people using GNU libc on SunOS are screwed by prototypes for the
+ standard library.
+
+ (Those who wish to compile clean with gcc -Wall on a standard
+ SunOS setup need the prototypes, and may obtain them using
+ -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
+ with nonstandard libraries are presumably competent to make their
+ own arrangements).
+
+ *) Strips trailing '/' characters off both args to the Alias command,
+ to make 'Alias /foo/ /bar/' work.
+
+Changes with Apache 0.8.7
+
+ *) Don't hang when restarting with a child from 'TransferLog "|..."' running
+ [reported by David Robinson]
+
+ *) Compiles clean on OSF/1 [David Robinson]
+
+ *) Added some of the more recent significant changes (AddLanguage stuff,
+ experimental LogFormat support) to CHANGES file in distribution root
+ directory
+
+Changes with Apache 0.8.6
+
+ *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
+ (If you actually wanted a conditional GET which bypassed the cache, you
+ couldn't get it). [Reported by Roy Fielding]
+
+ *) Properly terminate headers on '304 Not Modified' replies to conditional
+ GETs --- no browser we can find cares much, but the CERN proxy chokes.
+ [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
+
+ *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
+
+ *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
+ not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
+ and older versions don't set the __SUNPRO_C preprocessor variable). On
+ all other systems, these are never used anyway. [Reported by Mark Cox].
+
+ *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
+
+Changes with Apache 0.8.5
+
+ *) Added last-minute configurable log experiment, as optional module
+
+ *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
+ properly. (One-line fix to http_protocol.c).
+
+ *) Work around bogus behavior when reloading from Netscape.
+ It's Netscape's bug --- for some reason they expect a request with
+ If-modified-since: to not function as a conditional GET if it also
+ comes with Pragma: no-cache, which is way out of line with the HTTP
+ spec (according to Roy Fielding, the redactor).
+
+ *) Added parameter to set maximum number of server processes.
+
+ *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg]
+
+ *) IdentityCheck bugfix [Chuck Murcko].
+
+ *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
+
+ *) More sample config file corrections; add extension to AddType for
+ *.asis, move AddType generic description to its proper place, and
+ fix miscellaneous typos. [ Alexei Kosut ]
+
+ *) Deleted the *other* reference to the regents from the Berkeley
+ legal disclaimer (everyplace).
+
+ *) Nuked Shambhala name from src/README; had already cleaned it out
+ of everywhere else.
+
+Changes with Apache 0.8.4
+
+ *) Changes to server-pool management parms --- renamed current
+ StartServers to MinSpareServers, created separate StartServers
+ parameter which means what it says, and renamed MaxServers to
+ MaxSpareServers (though the old name still works, for NCSA 1.4
+ back-combatibility). The old names were generally regarded as
+ too confusing. Also altered "docs" in sample config files.
+
+ *) More improvements to default config files ---
+ sample directives (commented out) for XBitHack, BindAddress,
+ CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
+ defaults, AddTypes for send-as-is and imagemap magic types, and
+ improvements to samples for DirectoryIndex [Alexei Kosut]
+
+ *) Yet more improvements to default config files --- changes to
+ Alexei's sample AddLanguage directives, and sample LanguagePriority
+ [ Florent Guillaume ]
+
+ *) Set config file locations properly if not set in httpd.conf
+ [ David Robinson ]
+
+ *) Don't escape URIs in internal redirects multiple times; don't
+ do that when translating PATH_INFO to PATH_TRANSLATED either.
+ [ David Robinson ]
+
+ *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
+
+Changes with Apache 0.8.3
+
+ *) Edited distribution README to *briefly* summarize installation
+ procedures, and give a pointer to the INSTALL file in the src/
+ directory.
+
+ *) Upgraded imagemap script in cgi-bin to 1.8 version from more
+ recent NCSA distributions.
+
+ *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
+ exist for the same directory, use both and don't segfault. [Reported
+ by David Robinson]
+
+ *) Proper makefile dependencies [David Robinson]
+
+ *) Note (re)starts in error log --- reported by Rob Hartill.
+
+ *) Only call no2slash() after get_path_info() has been done, to
+ preserve multiple slashes in the PATH_INFO [NCSA compatibility,
+ reported by Andrew Wilson, though this one is probably a real bug]
+
+ *) Fixed mod_imap.c --- relative paths with base_uri referer don't
+ dump core when Referer is not supplied. [Randy Terbush]
+
+ *) Lightly edited sample config files to refer people to our documentation
+ instead of NCSA's, and to list Rob McCool as *original* author (also
+ deleted his old, and no doubt non-functional email address). Would be
+ nice to have examples of new features...
+
+Changes with Apache 0.8.2
+
+ *) Added AddLanuage code [Florent Guillaume]
+
+ *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
+
+ *) All sorts of problems when MultiViews finds a directory. It would
+ be nice if mod_dir.c was robust enough to handle that, but for now,
+ just punt. [reported by Brian Behlendorf]
+
+ *) Wait for all children on restart, to make sure that the old socket
+ is gone and we can reopen it. [reported by Randy Terbush]
+
+ *) Imagemap module is enabled in default Configuration
+
+ *) RefererLog and UserAgentLog modules properly default the logfile
+ [Randy Terbush]
+
+ *) Mark Cox's mod_cookies added to the distribution as an optional
+ module (commented out in the default Configuration, and noted as
+ an experiment, along with mod_dld). [Mark Cox]
+
+ *) Compiles on Ultrix (a continuing battle...). [Robert Thau]
+
+ *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
+
+ *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
+
+ *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
+ license]
+
+Changes with Apache 0.8.1
+
+ *) New imagemap module [Randy Terbush]
+
+ *) Replacement referer log module with NCSA-compatible RefererIgnore
+ [Matthew Gray again]
+
+ *) Don't mung directory listings with very long filenames.
+ [Florent Guillaume]
+
+Changes with Apache 0.8.0 (nee Shambhala 0.6.2):
+
+ *) New config script. See INSTALL for info. [Robert Thau]
+
+ *) Scoreboard mechanism for regulating the number of extant server
+ processes. MaxServers and StartServers defaults are the same as
+ for NCSA, but the meanings are slightly different. (Actually,
+ I should probably lower the MaxServers default to 10).
+
+ Before asking for a new connection, each server process checks
+ the number of other servers which are also waiting for a
+ connection. If there are more than MaxServers, it quietly dies
+ off. Conversely, every second, the root, or caretaker, process
+ looks to see how many servers are waiting for a new connection;
+ if there are fewer than StartServers, it starts a new one. This
+ does not depend on the number of server processes already extant.
+ The accounting is arranged through a "scoreboard" file, named
+ /tmp/htstatus.*, on which each process has an independant file
+ descriptor (they need to seek without interference).
+
+ The end effect is that MaxServers is the maximum number of
+ servers on an *inactive* server machine, but more will be forked
+ off to handle unusually heavy loads (or unusually slow clients);
+ these will die off when they are no longer needed --- without
+ reverting to the overhead of full forking operation. There is a
+ hard maximum of 150 server processes compiled in, largely to
+ avoid forking out of control and dragging the machine down.
+ (This is arguably too high).
+
+ In my server endurance tests, this mechanism did not appear to
+ impose any significant overhead, even after I forced it to put the
+ scoreboard file on a normal filesystem (which might have more
+ overhead than tmpfs). [Robert Thau]
+
+ *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
+ [Cliff Skolnick]
+
+ *) Read .htaccess files even in directory with <Directory> section.
+ (Former incompatibility noted on mailing list, now fixed). [Robert
+ Thau]
+
+ *) "HEAD /" gives the client a "Bad Request" error message, rather
+ than trying to send no body *and* no headers. [Cliff Skolnick].
+
+ *) Don't produce double error reports for some very obscure cases
+ mainly involving auth configuration (the "all modules decline to
+ handle" case which is a sure sign of a server bug in most cases,
+ but also happens when authentication is badly misconfigured).
+ [Robert Thau]
+
+ *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
+ it's *for*, and this sort of thing really shouldn't be cluttering
+ up the Makefile). [Robert Thau]
+
+ *) Incidental code cleanups in http_main.c --- stop dragging
+ sa_client around; just declare it where used. [Robert Thau]
+
+ *) Another acc-related fix. (It doesn't like const char
+ in some places...). [Mark Cox]
+
+Changes with 0.6.1
+
+ *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
+ Also, fixed auth typo in http_protocol.c unmasked by this fix.
+
+ *) Compiles clean with acc on SunOS [Paul Sutton]
+
+ *) Reordered modules in modules.c so that Redirect takes priority
+ over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
+ believe it or not, he has an actual site with a ScriptAlias and
+ a Redirect declared for the *exact same directory*. Even *my*
+ compatibility fetish wouldn't motivate me to fix this if the fix
+ required any effort, but it doesn't, so what the hey.
+
+ *) Fixed to properly default several server_rec fields for virtual
+ servers from the corresponding fields in the main server_rec.
+ [Cliff Skolnick --- 'port' was a particular irritant].
+
+ *) No longer kills off nph- child processes before they are
+ finished sending output. [Matthew Gray]
+
+Changes with 0.6.0
+
+ *) Two styles of timeout --- hard and soft. soft_timeout()s just put
+ the connection to the client in an "aborted" state, but otherwise
+ allow whatever handlers are running to clean up. hard_timeout()s
+ abort the request in progress completely; anything not tied to some
+ resource pool cleanup will leak. They're still around because I
+ haven't yet come up with a more elegant way of handling
+ timeouts when talking to something that isn't the client. The
+ default_handler and the dir_handler now use soft timeouts, largely
+ so I can test the feature. [Robert Thau]
+
+ *) TransferLog "| my_postprocessor ..." seems to be there. Note that
+ the case of log handlers dying prematurely is probably handled VERY
+ gracelessly at this point, and if the logger stops reading input,
+ the server will hang. (It is known to correctly restart the
+ logging process on server restart; this is (should be!) going through
+ the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
+ script). [Robert Thau]
+
+ *) asis files supported (new module). [Robert Thau]
+
+ *) IdentityCheck code is compiled in, but has not been tested. (I
+ don't know anyone who runs identd). [Robert Thau]
+
+ *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
+ came in with the request, for NCSA bug-compatibility. [Robert Thau]
+
+ *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
+
+ *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
+ as timeouts are not in scope. [Robert Thau]
+
+ *) quoted-string args in config files now handled correctly (doesn't drop
+ the last character). [Robert Thau; reported by Randy Terbush]
+
+ *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
+ How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
+
+ *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
+ default default type); the former default default behavior when all
+ type-checkers defaulted had been a core dump. [Paul Sutton]
+
+ *) Copy filenames out of the struct dirent when indexing
+ directories. (On Linux, readdir() returns a pointer to the same
+ memory area every time). Fix is in mod_dir.c. [Paul Sutton]
+
+Changes with 0.5.3 [not released]
+
+ *) Default response handler notes "file not found" in the error log,
+ if the file was not found. [Cliff Skolnick].
+
+ *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
+ code no longer sets up bogus PATH_INFO which fakes out the directory
+ handler). [Cliff Skolnick]
+
+Changes with 0.5.2
+
+ *) Changes to http_main.c --- root server no longer plays silly
+ games with SIGCHLD, and so now detects and replaces dying
+ children. Child processes just die on SIGTERM, without taking
+ the whole process group with them. Potential problem --- if any
+ child process refuses to die, we hang in restart.
+ MaxRequestsPerChild may still not work, but it certainly works
+ better than it did before this! [Robert Thau]
+
+ *) mod_dir.c bug fixes: ReadmeName and HeaderName
+ work (or work better, at least); over-long description lines
+ properly terminated. [Mark Cox]
+
+ *) http_request.c now calls unescape_url() more places where it
+ should [Paul Sutton].
+
+ *) More directory handling bugs (reported by Cox)
+ Parent Directory link is now set correctly. [Robert Thau]
+
+Changes with 0.5.1: [Hopefully complete]
+
+ *) Generalized cleanup interface in alloc.c --- any function can be
+ registered with alloc.c as a cleanup for a resource pool;
+ tracking of files and file descriptors has been reimplemented in
+ terms of this interface, so I can give it some sort of a test.
+ [Robert Thau]
+
+ *) More changes in alloc.c --- new cleanup_for_exec() function,
+ which tracks down and closes all file descriptors which have been
+ registered with the alloc.c machinery before the server exec()s a
+ child process for CGI or <!--#exec-->. CGI children now get
+ started with exactly three file descriptors open. Hopefully,
+ this cures the problem Rob H. was having with overly persistent
+ CGI connections. [Robert Thau]
+
+ *) Mutual exclusion around the accept() in child_main() --- this is
+ required on at least SGI, Solaris and Linux, and is #ifdef'ed in
+ by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
+ This uses fcntl(F_SETLK,...) on the error log descriptor because
+ flock() on that descriptor won't work on systems which have BSD
+ flock() semantics, including (I think) Linux 1.3 and Solaris.
+
+ This does work on SunOS (when the server is idle, only one
+ process in the pool is waiting on accept()); it *ought* to work
+ on the other systems. [Robert Thau]
+
+ *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
+
+ *) sizeof(*sa_client) bugfix from [Rob Hartill]
+
+ *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
+
+ *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
+ be unnecessary if I go to the revised timeout-handling scheme).
+ [Robert Thau]
+
+ *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
+ string) even if none came in with the request. [Robert Thau]
+
+ *) CHANGES file added to distribution ;-).

+This release of Apache supports the notion of "optional modules".
+However, the server has to know which modules are compiled into it, in
+order for those modules to be effective; this requires generation of a
+short bit of code ("modules.c") which simply has a list of them.
+
+It is also necessary to choose the correct options for your platform.
+
+To do this:
+
+1) Copy the file "Configuration.tmpl" to "Configuration" and then edit
+ "Configuration". This contains the per-machine config settings of
+ the Makefile, and also an additional section at the bottom which
+ lists the modules which have been compiled in, and also names the
+ files containing them. You will need to:
+
+ a) Select a compiler, and compilation options as appropriate to
+ your machine.
+
+ b) Uncomment lines corresponding to those optional modules you wish
+ to include (among the Module lines at the bottom of the file),
+ or add new lines corresponding to custom modules you have written.
+ (See API.html for preliminary docs on how to do that).
+
+ Note that DBM auth has to be explicitly configured in, if you want
+ it --- just uncomment the corresponding line.
+
+2) Run the "Configure" script:
+
+ % Configure
+ Using 'Configuration' as config file
+ %
+
+ This generates new versions of the Makefile and of modules.c. (If
+ you want to maintain multiple configurations, you can say, e.g.,
+
+ % Configure -file Configuration.ai
+ Using alternate config file Configuration.ai
+ %
+
+3) Type "make".
+
+The modules we place in the Apache distribution are the ones we have
+tested and are used regularly by various members of the Apache

+The basic idea of the new Apache release is to make a modular
+"tinkertoy" server, to which people can easily add code which is
+valuable to them (even if it isn't universally useful) without hairing
+up a monolithic server. Applications for this idea include database
+integration, support for experimental search and scripting extensions,
+new authentication modes (digest authentication, for instance, could
+be done entirely as a module), and so forth. All modules have the
+same interface to the server core, and through it, to each other.
+
+In particular, the following are modules in the current code base:
+common log format (other loggers can easily coexist with it), auth and
+dbm auth (although both use common code in http_protocol.c to parse
+the Authorization: line), directory handling (which can be added or
+replaced), handling of aliases and access control, content
+negotiation, CGI, includes, aliases, and so forth. (What's left in
+the basic server? Not a whole lot). The configuration file commands
+which configure these things are defined, for the most part, by the
+modules themselves, and not by the server core (each module has, or
+can have, a command dispatch table).
+
+Besides carving up the base code into modules, this release makes a
+few other fairly pervasive changes. Most of the global variables are
+gone; most of the MAX_STRING_LENGTH char arrays are gone (the few that
+are left being sprintf() targets, or I/O buffers of various sorts),
+and unmunge_name has vanished. The most drastic change is the use of
+a "compool" strategy to manage resources allocated for a request ---
+the code in alloc.c keeps track of it all and allows it to be freed en
+bloc at the end of the request. This strategy seems to be effective
+in stanching memory and descriptor leaks.
+
+Additional third-party modules can be found at
+<URL:http://www.apache.org/dist/contrib/modules/>.
+
+
+A brief code review:
+
+The code here can be divided into the server core (the http_* files,
+along with alloc.c and the various utility files), and several modules
+(the mod_* files).
+
+The core interfaces to modules through the "module" structure which
+describes each one. There's a linked list of these things rooted at
+top_module, through which http_config.c dispatches when necessary. The
+module structures themselves are defined at the bottom of the mod_foo
+files. (Loading new modules dynamically at runtime should be simple;
+just push them onto the linked list. The only complication is what to
+do with AddModule commands when the config files are reread,
+particularly if you find a module has been taken out).
+
+In addition to the core itself (which does have a module structure to
+hold its command tables, and the handlers for various phases of
+request handling which make it *barely* a web server on its own),
+the modules included here are the following:
+
+mod_mime.c --- deduction of MIME types and content-encodings from
+ filename extensions. This module defines the AddType, AddEncoding,
+ and TypesConfig config-file directives. This code is off in a
+ module by itself so that people who want to experiment with other
+ meta-information schemes can replace it, and still have content
+ negotiation work.
+
+mod_common_log.c --- logging in common log format.
+
+mod_auth.c --- HTTP authentication. Defines the AuthUserFile and
+ AuthGroupFile directives (other auth-related commands are handled by
+ the core itself, so it knows which requests require it to poll the
+ modules for authentication handlers).
+
+mod_auth_dbm.c --- DBM auth. Untested, and left out of the modules
+ list in modules.c because of that, but it does at least compile.
+ Grump.
+
+mod_access.c --- access checking by DNS name or IP address; defines
+ the "order", "allow" and "deny" config-file commands. (If this
+ module is compiled out, the server fails safe --- any attempt to
+ configure access control will die on a config file syntax error when
+ the relevant commands go unrecognized).
+
+mod_negotiation.c --- Content negotiation. Defines the
+ CacheNegotiatedDocs config-file command. Making this a module is
+ perhaps going overboard, but I wanted to see how far I could push
+ it.
+
+mod_alias.c --- Alias command and file translation.
+
+mod_userdir.c --- ditto for Userdir.
+
+mod_cgi.c --- Common Gateway Interface. Also defines ScriptAlias,
+ because scripts are treated slightly differently depending on
+ whether they are ScriptAliased or not (in particular, ExecCGI is not
+ required in the former case).
+
+mod_includes.c --- server-side includes.
+
+mod_dir.c --- defines a whole *raft* of commands; handles directories.
+
+mod_asis.c --- ASIS file handling.
+
+mod_dld.c --- the experimental runtime-code-loader described above.
+ You'll have to alter the makefile and modules.c to make this active
+ if you want it.
+
+
+
+As to the core, here's a brief review of what's where:
+
+http_protocol.c --- functions for dealing directly with the client.
+ Reading requests, writing replies of various sorts. I've tried to
+ route all data transfer between server and client through here, so
+ there's a single piece of code to change if we want to add, say,
+ HTTP-NG packetization. The major glaring exception is NPH- CGI
+ scripts; what *will* we do with those for HTTP-NG?
+
+http_request.c --- functions which direct the processing of requests,
+ including error handling. Generally responsible for making sure
+ that the right module handlers get invoked, in the right order.
+ (This includes the "sub-request" mechanism, which is used by
+ includes and other stuff to ask about the status of particular
+ subfiles).
+
+http_core.c ---
+ Contains the core module structure, its command table, and the
+ command handlers, also the filename translation routine, and the
+ like for the core. (Basically, this is all of the core module stuff
+ which looks more or less like the boilerplate from the other modules).
+
+http_config.c --- Functions to read config files and dispatch to the
+ command handlers; also, routines to manage configuration vectors,
+ and to dispatch to modules' handlers for the various phases of
+ handling a request.
+
+http_log.c --- just the error log. Error handling is split between
+ http_protocol.c (for generating the default error responses) and
+ http_request.c (for executive handling, including ErrorDocument
+ invocation); transaction logging is in the modules.
+
+http_main.c --- System startup, restart, and accepting connections;
+ also timeout handling (which is pretty grotesque right now; ideas?)
+
+alloc.c --- allocation of all resources which might have to be reclaimed
+ eventually, including memory, files, and child processes.
+
+ =================================================
+List of various #defines used in the code:
+The Apache code, specifically in conf.h, uses a variety of #defines to
+control how the code is compiled and what options are available for each
+support OS. The following list provides a short list and description
+of these #defines.
+
+--
+
+ NEED_*:
+ If the particular OS doesn't supply the specified function, we use the
+ Apache-supplied version (in util.c).
+
+ NEED_STRERROR:
+ NEED_STRDUP:
+ NEED_STRCASECMP:
+ NEED_STRNCASECMP:
+ NEED_INITGROUPS:
+ NEED_WAITPID:
+ NEED_STRERROR:
+ NEED_SELECT_H:
+ Define if the OS needs the <sys/select.h> header file.
+
+--
+
+ HAVE_*:
+ Does this OS have/support this capablity?
+
+ HAS_GMTOFF:
+ Define if the OS's tm struct has the tm_gmtoff element
+
+ HAVE_RESOURCE:
+ Define as 1 if the OS supports the getrlimit()/setrlimit() functions
+
+ HAVE_MMAP:
+ Define if the OS supports the BSD mmap() call. This is used by various
+ OSs to allow the scoreboard file to be held in shared mmapped-memory
+ instead of a real file.
+
+ HAVE_SHMGET:
+ Define if the OS has the SysV-based shmget() family of shared-memory
+ functions. Used to allow the scoreboard to live in a shared-memory
+ slot instead of a real file.
+
+ HAVE_CRYPT_H:
+ Define if the OS has the <crypt.h> header file.
+
+--
+
+ NO_*:
+ These are defined if the OS does NOT have the specified function or if
+ we should not use it.
+
+ NO_KILLPG:
+ NO_SETSID:
+ NO_USE_SIGACTION:
+ Do not use the sigaction() call, even if we have it.
+--
+
+ MISC #DEFINES:
+ Various other #defines used in the code.
+
+ FCNTL_SERIALIZED_ACCEPT:
+ Define if the OS requires a mutex "lock" around the socket accept()
+ call. Use fcntl() locking.
+
+ FLOCK_SERIALIZED_ACCEPT:
+ Define if the OS requires a mutex "lock" around the socket accept()
+ call. Use flock() locking (fcntl() is expensive on some OSs, esp.
+ when using NFS).
+
+ JMP_BUF:
+ The variable-type for siglongjmp() or longjmp() call.
+
+ MOVEBREAK:
+ Amount to move sbrk() breakpoint, if required, before attaching
+ shared-memory segment.

+ * Routines in http_main.c which other code --- in particular modules ---
+ * may want to call. Right now, that's limited to timeout handling.
+ * There are two functions which modules can call to trigger a timeout
+ * (with the per-virtual-server timeout duration); these are hard_timeout
+ * and soft_timeout.
+ *
+ * The difference between the two is what happens when the timeout
+ * expires (or earlier than that, if the client connection aborts) ---
+ * a soft_timeout just puts the connection to the client in an
+ * "aborted" state, which will cause http_protocol.c to stop trying to
+ * talk to the client, but otherwise allows the code to continue normally.
+ * hard_timeout(), by contrast, logs the request, and then aborts it
+ * completely --- longjmp()ing out to the accept() loop in http_main.
+ * Any resources tied into the request's resource pool will be cleaned up;
+ * everything that isn't will leak.
+ *
+ * soft_timeout() is recommended as a general rule, because it gives your
+ * code a chance to clean up. However, hard_timeout() may be the most
+ * convenient way of dealing with timeouts waiting for some external
+ * resource other than the client, if you can live with the restrictions.
+ *
+ * (When a hard timeout is in scope, critical sections can be guarded
+ * with block_alarms() and unblock_alarms() --- these are declared in
+ * alloc.c because they are most often used in conjunction with
+ * routines to allocate something or other, to make sure that the
+ * cleanup does get registered before any alarm is allowed to happen
+ * which might require it to be cleaned up; they * are, however,
+ * implemented in http_main.c).
+ *
+ * kill_timeout() will disarm either variety of timeout.
+ *
+ * reset_timeout() resets the timeout in progress.

+/* User Tracking Module
+ *
+ * This Apache module is designed to track users paths through a site.
+ * It uses the client-side state ("Cookie") protocol developed by Netscape.
+ * It is known to work on Netscape browsers, Microsoft Internet
+ * Explorer and others currently being developed.
+ *
+ * Each time a page is requested we look to see if the browser is sending
+ * us a Cookie: header that we previously generated.
+ *
+ * If we don't find one then the user hasn't been to this site since
+ * starting their browser or their browser doesn't support cookies. So
+ * we generate a unique Cookie for the transaction and send it back to
+ * the browser (via a "Set-Cookie" header)
+ * Future requests from the same browser should keep the same Cookie line.
+ *
+ * The cookie and request are logged to a file. Use the directive
+ * "CookieLog somefilename" in one of the config files to enable the Cookie
+ * module. By matching up all the requests with the same cookie you can
+ * work out exactly what path a user took through your site.
+ *
+ * Notes:
+ * 1. This code doesn't log the initial transaction (the one that created
+ * the cookie to start with). If it did then the cookie log file would
+ * be bigger than a normal access log.
+ * 2. This module has been designed to not interfere with other Cookies
+ * your site may be using; just avoid sending out cookies with
+ * the name "Apache=" or things will get confused.
+ * 3. If you want you can modify the Set-Cookie line so that the Cookie
+ * never expires. You would then get the same Cookie each time the
+ * user revisits your site.
+ *
+ * Mark Cox, mark@ukweb.com, http://www.ukweb.com/~mark/, 6 July 95
+ *
+ * 6.12.95 MJC Now be more friendly. Allow our cookies to overlap with
+ * others the site may be using. Use a more descriptive
+ * cookie name.
+ *
+ * 18.3.96 MJC Generate cookies for EVERY request no matter what the
+ * browser. We never know when a new browser writer will
+ * add cookie support.
+ *
+ * 96/03/31 -JimC Allow the log to be sent to a pipe. Copies the relevant
+ * code from mod_log_agent.c.
+ *
+ * 24.5.96 MJC Improved documentation after receiving comments from users

+Note that the Explain() stuff is not yet complete.
+Also note numerous FIXMEs and CHECKMEs which should be eliminated.
+
+If TESTING is set, then garbage collection doesn't delete ... probably a good
+idea when hacking.
+
+This code is still experimental!
+
+Things to do:
+
+1. Make it garbage collect in the background, not while someone is waiting for
+a response!
+
+2. Check the logic thoroughly.
+
+3. Empty directories are only removed the next time round (but this does avoid
+two passes). Consider doing them the first time round.
+
+Ben Laurie 30 Mar 96
+
+More changes:
+
+0) tested w/SOCKS proxy for http
+1) fixed IP address formation in host2addr()
+2) fixed SIGALRM on big cache cleanup
+3) fixed temp files #tmp not removed
+4) changed PF_INET to AF_INET in socket() calls
+5) installed CONNECT code from Troy Morrison for testing
+6) added NoCache config directive to disallow caching for selected hosts

+ * Adapted for Berkeley DB by Andrew Cohen
+ *
+ * mod_auth_db was based on mod_auth_dbm.
+ *
+ * Warning, this is not a drop in replacement for mod_auth_dbm,
+ * for people wanting to switch from dbm to Berkeley DB.
+ * It requires the use of AuthDBUserFile and AuthDBGroupFile
+ * instead of AuthDBMUserFile AuthDBMGroupFile
+ *
+ * Also, in the configuration file you need to specify
+ * db_auth_module rather than dbm_auth_module
+ *
+ * On some BSD systems (e.g. FreeBSD and NetBSD) dbm is automatically
+ * mapped to Berkeley DB. You can use either mod_auth_dbm or
+ * mod_auth_db. The latter makes it more obvious that it's Berkeley.

+ * mod_auth_msql: authentication
+ *
+ * Rob McCool & Brian Behlendorf.
+ *
+ * Adapted to Shambhala by rst.
+ *
+ * Addapted for use with the mSQL database
+ * (see ftp:/ftp.bond.edu.au/pub/Minerva/mSQL)
+ *
+ * Version 1.0 May 1996 - Blame: Dirk.vanGulik@jrc.it.
+ *
+ * A (sometimes more up to date) version of the documentation
+ * can be found at the http://www.apache.org site or at
+ * http://me-www.jrc.it/~dirkx/mod_auth_msql.html.
+ *
+ * Outline:
+ *
+ * This module allows access control using the public domain
+ * mSQL database; a fast but limted SQL engine which can be
+ * contacted over an internal unix domain protocol as well as
+ * over normal inter-machine tcp/ip socket communication.
+ *
+ * An example table could be:
+ *
+ * create table user_records (
+ * User_id char(32) primary key,
+ * Cpasswd char(32),
+ * [ Xgroup char(32) ]
+ * ) \g
+ *
+ * The user_id can be as long as desired; however some of the
+ * popular web browsers truncate, or stop the user from entering
+ * names longer than 32 characters. Furthermore the 'crypt' function
+ * on your platform might impose further limits. Also use of
+ * the 'require users uid [uid..]' directive in the access.conf file,
+ * where the user ids are separated by spaces can possibly prohibit the
+ * use of spaces in your user-names. Also, not the MAX_FIELD_LEN define
+ * somewhere below.
+ *
+ * To use the above, the following example could be in your access.conf
+ * file. Also there is a more elaborate description afther this example.
+ *
+ *
+ *
+ * Auth_MSQLhost localhost
+ * or
+ * Auth_MSQLhost datab.machine.your.org
+ *
+ * If this directive is ommited, or set to
+ * localhost, the machine on which apache
+ * runs is assumed, and the faster /dev/msql
+ * communication channel will be used. Otherwise
+ * it is the machine to contact by tcp/ip.
+ *
+ * Auth_MSQLdatabase www
+ *
+ * The name of the database on the above machine,
+ * which contains *both* the tables for group and
+ * for user/passwords. Currently it is not possible
+ * to have these split over two databases. Make
+ * sure that the msql.acl (access control file) of
+ * mSQL does indeed allow the effective uid of the
+ * web server read access to this database. Check the
+ * httpd.conf file for this uid.
+ *
+ * Auth_MSQLpwd_table user_records
+ *
+ * Here the table which contain the uid/password combination
+ * is specified.
+ *
+ * Auth_MSQLuid_field User_id
+ * Auth_MSQLpwd_field Cpasswd
+ *
+ * These two directive specify the field names in the 'user_record'
+ * table. If this module is compiled with the BACKWARD_VITEK
+ * compatibility switch, the defaults 'user' and 'password' are
+ * assumed if you do not specify them. Currently the user_id field
+ * *MUST* be a primary key or one must ensure that each user only
+ * occurs *once* in the table. If a UID occurs twice access is
+ * denied by default.
+ *
+ * Auth_MSQLgrp_table user_records
+ * Auth_MSQLgrp_field Xgroup
+ *
+ * Optionaly one can also specify a table which contains the
+ * user/group combinations. This can be the same table which
+ * also contains the username/password combinations. However
+ * if a user belongs to two or more groups, one will have to
+ * use a differt table with multiple entries.
+ *
+ * Auth_MSQL_nopasswd off
+ * Auth_MSQL_Authorative on
+ * Auth_MSQL_EncryptedPasswords on
+ *
+ * These three optional fields (all set to the sensible defaults,
+ * so you really do not have to enter them) are described in more
+ * detail below. If you choose to set these to any other values than
+ * the above be very sure you understand the security implications and
+ * do verify that apache does what you exect it to do.
+ *
+ * AuthName example mSQL realm
+ * AuthType basic
+ *
+ * Normal apache/ncsa tokens for access control
+ *
+ *
+ * order deny,allow
+ * allow from all
+ *
+ * require valid-user
+ * 'valid-user'; allow in any user which has a valid uid/passwd
+ * pair in the above pwd_table.
+ * or
+ * require user smith jones
+ * Limit access to users who have a valid uid/passwd pair in the
+ * above pwd_table AND whose uid is 'smith' or 'jones'. Do note that
+ * the uid's are separated by 'spaces' for historic (ncsa) reasons.
+ * So allowing uids with spaces might cause problems.
+ *
+ * require group has_paid
+ * Optionally also ensure that the uid has the value 'has_paid' in the group
+ * field in the group table.
+ *
+ *
+ *
+ * End of the example
+ *
+ * - full description of all tokens: -
+ *
+ * Directives:
+ *
+ * Auth_MSQLhost Hostname of the machine running
+ * the mSQL demon. The effective uid
+ * of the server should be allowed
+ * access. If not given, or if it is
+ * the magic name 'localhost', it is
+ * passed to the mSQL libary as a null
+ * pointer. This effectively forces it
+ * to use /dev/msql rather than the
+ * (slower) socket communication.
+ *
+ * Auth_MSQLdatabase Name of the database in which the following
+ * table(s) are contained.
+ *
+ * Auth_MSQLpwd_table Contains at least the fields with the
+ * username and the (encrypted) password. Each
+ * uid should only occur once in this table and
+ * for performance reasons should be a primary key.
+ * Normally this table is compulsory, but it is
+ * possible to use a fall-through to other methods
+ * and use the mSQL module for group control only;
+ * see the Authorative directive below.
+ *
+ * Auth_MSQLgrp_table Contains at least the fields with the
+ * username and the groupname. A user which
+ * is in multiple groups has therefore
+ * multiple entries; this might be some per-
+ * formance problems associated with this; and one
+ * might consider to have separate tables for each
+ * group (rather than all groups in one table) if
+ * your directory structure allows for it.
+ * One only needs to specify this table when doing
+ * group control.
+ *
+ * Auth_MSQLuid_field Name of the field containing the username
+ * Auth_MSQLpwd_field Fieldname for the passwords
+ * Auth_MSQLgrp_field Fieldname for the groupname
+ *
+ * Only the fields used need to be specified. When this
+ * module is compiled with the BACKWARD_VITEK option the
+ * uid and pwd field names default to 'user' and 'password'.
+ *
+ *
+ * Auth_MSQL_nopasswd
+ * skip password comparison if passwd field is
+ * empty; i.e. allow 'any' password. This is off
+ * by default; thus to ensure that an empty field
+ * in the mSQL table does not allow people in by
+ * default with a random password.
+ *
+ * Auth_MSQL_Authorative
+ * default is 'on'. When set on, there is no
+ * fall through to other authorization methods. So if a
+ * user is not in the mSQL dbase table (and perhaps
+ * not in the right group) or has the password wrong, then
+ * he or she is denied access. When this directive is set to
+ * 'off' control is passed on to any other authorization
+ * modules, such as the basic auth module wih the htpasswd
+ * file and or the unix-(g)dbm modules.
+ * The default is 'ON' to avoid nasty 'fall-through' sur-
+ * prizes. Do be sure you know what you decide to switch
+ * it off.
+ *
+ * Auth_MSQL_EncryptedPasswords
+ * default is on. When set on, the values in the
+ * pwd_field are assumed to be crypted using *your*
+ * machines 'crypt' function; and the incoming password
+ * is 'crypt'ed before comparison. When this function is
+ * off, the comparison is done directly with the plaintext
+ * entered password. (Yes; http-basic-auth does send the
+ * password as plaintext over the wire :-( ). The default
+ * is a sensible 'on', and I personally thing that it is
+ * a *very-bad-idea* to change this. However a multi
+ * vendor or international environment (which sometimes
+ * leads to different crypts functions) might force you to.

+ *
+ * Version 0.0 First release
+ * 0.1 Update to apache 1.00
+ * 0.2 added lines which got missing god knows when
+ * and which did the valid-user authentification
+ * no good at all !
+ * 0.3 Added 'Auth_MSQL_nopasswd' option
+ * 0.4 Cleaned out the error messages mess.
+ * 0.6 Inconsistency with gid/grp in comment/token/source
+ * Make sure you really use 'Auth_MSQLgrp_field' as
+ * indicated above.
+ * 0.7 *host to host fixed. Credits go to Rob Stout,
+ * for spotting this one.
+ * 0.8 Authorative directive added. See above.
+ * 0.9 palloc return code check(s), should be backward compatible with
+ * 1.11 version of Vivek Khera msql module,
+ * fixed broken err msg in group control, changed command table
+ * messages to make more sense when displayed in that new module
+ * management tool. Added EncryptedPassword on/off functionality.
+ * msqlClose() statements added upon error. Support for persistent
+ * connections with the mSQL database (riscy). Escaping of ' and \.
+ * Replaced some MAX_STRING_LENGTH claims.
+ * 1.0 removed some error check as they where already done elsehwere
+ * NumFields -> NumRows (Thanks Vitek). More stack memory.

+#define ONLY_ONCE 1
+/*
+ * If the mSQL table containing the uid/passwd combination does
+ * not have the uid field as a primary key, it is possible for the
+ * uid to occur more than once in the table with possibly different
+ * passwords. When this module is compiled with the ONLY_ONCE directive
+ * set, access is denied if the uid occures more than once in the
+ * uid/passwd table. If you choose not to set it, the software takes
+ * the first pair returned and ignores any further pairs. The SQL
+ * statement used for this is
+ *
+ * "select password form pwd_table where user='uid'"
+ *
+ * this might lead to unpredictable results. For this reason as well
+ * as for performance reasons you are strongly adviced to make the
+ * uid field a primary key. Use at your own peril :-)
+ */
+
+#undef KEEP_MSQL_CONNECTION_OPEN
+/*
+ * Normally the (tcp/ip) connection with the database is opened and
+ * closed for each SQL query. When the httpd-server and the database
+ * are on the same machine, and /dev/msql is used this does not
+ * cause a serious overhead. However when your platform does not
+ * support this (see the mSQL documentation) or when the web server
+ * and the database are on different machines the overhead can be
+ * considerable. When the above is set defined the server leaves the
+ * connection open; i.e. no call to msqlClose(). If an error occures
+ * an attempt is made to re-open the connection for the next http-rq.
+ *
+ * This has a number of very serious drawbacks
+ * - It costs 2 already rare filedescriptors for each child.
+ * - It costs msql-connections, typically one per child. The (compiled in)
+ * number of connections mSQL can handle is low, typically 6 or 12.
+ * which might prohibit access to the mSQL database for later
+ * processes.
+ * - when a child dies, it might not free that connection properly
+ * or quick enough.
+ * - When errors start to occur, connection/file-descr resources might
+ * become exausted very quickly.
+ *
+ * In short; use this at your own peril and only in a highly controled and
+ * monitored environment

+ * mod_cern_meta.c
+ * version 0.0.5
+ * status beta
+ *
+ * Andrew Wilson 25.Jan.96
+ *
+ * Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP
+ * headers that can be output in addition to the normal range of
+ * headers for each file accessed. They appear rather like the Apache
+ * .asis files, and are able to provide a crude way of influencing
+ * the Expires: header, as well as providing other curiosities.
+ * There are many ways to manage meta information, this one was
+ * chosen because there is already a large number of CERN users
+ * who can exploit this module. It should be noted that there are probably
+ * more sensitive ways of managing the Expires: header specifically.
+ *
+ * The module obeys the following directives, which can only appear
+ * in the server's .conf files and not in any .htaccess file.
+ *
+ * MetaDir
+ *
+ * specifies the name of the directory in which Apache can find
+ * meta information files. The directory is usually a 'hidden'
+ * subdirectory of the directory that contains the file being
+ * accessed. eg:
+ *
+ * # .meta files are in the *same* directory as the
+ * # file being accessed
+ * MetaDir .
+ *
+ * the default is to look in a '.web' subdirectory. This is the
+ * same as for CERN 3.+ webservers and behaviour is the same as
+ * for the directive:
+ *
+ * MetaDir .web
+ *
+ * MetaSuffix
+ *
+ * specifies the file name suffix for the file containing the
+ * meta information. eg:
+ *
+ * # our meta files are suffixed with '.cern_meta'
+ * MetaSuffix .cern_meta
+ *
+ * the default is to look for files with the suffix '.meta'. This
+ * behaviour is the same as for the directive:
+ *
+ * MetaSuffix .meta
+ *
+ * When accessing the file
+ *
+ * DOCUMENT_ROOT/somedir/index.html
+ *
+ * this module will look for the file
+ *
+ * DOCUMENT_ROOT/somedir/.web/index.html.meta
+ *
+ * and will use its contents to generate additional MIME header
+ * information.
+ *
+ * For more information on the CERN Meta file semantics see:
+ *
+ * http://www.w3.org/hypertext/WWW/Daemon/User/Config/General.html#MetaDir
+ *
+ * Change-log:
+ * 29.Jan.96 pfopen/pfclose instead of fopen/fclose
+ * DECLINE when real file not found, we may be checking each
+ * of the index.html/index.shtml/index.htm variants and don't
+ * need to report missing ones as spurious errors.
+ * 31.Jan.96 log_error reports about a malformed .meta file, rather
+ * than a script error.

+ * mod_env.c

+ * status beta
+ * Pass environment variables to CGI/SSI scripts.
+ *
+ * Andrew Wilson 06.Dec.95
+ *
+ * Change log:
+ * 08.Dec.95 Now allows PassEnv directive to appear more than once in
+ * conf files.
+ * 10.Dec.95 optimisation. getenv() only called at startup and used
+ * to build a fast-to-access table. table used to build
+ * per-server environment for each request.
+ * robustness. better able to handle errors in configuration
+ * files:
+ * 1) PassEnv directive present, but no environment variable listed
+ * 2) PassEnv FOO present, but $FOO not present in environment
+ * 3) no PassEnv directive present
+ * 23.Dec.95 Now allows SetEnv directive with same semantics as 'sh' setenv:
+ * SetEnv Var sets Var to the empty string
+ * SetEnv Var Val sets Var to the value Val
+ * Values containing whitespace should be quoted, eg:
+ * SetEnv Var "this is some text"
+ * Environment variables take their value from the last instance
+ * of PassEnv / SetEnv to be reached in the configuration file.
+ * For example, the sequence:
+ * PassEnv PATH
+ * SetEnv PATH /special/path
+ * Causes PATH to take the value '/special/path'.
+ * 23.Feb.96 Added UnsetEnv directive to allow environment variables
+ * to be removed.
+ * Virtual hosts now 'inherit' parent server environment which
+ * they're able to overwrite with their own directives or
+ * selectively ignore with UnsetEnv.
+ * *** IMPORTANT - the way that virtual hosts inherit their ***
+ * *** environment variables from the default server's ***
+ * *** configuration has changed. You should test your ***
+ * *** configuration carefully before accepting this ***
+ * *** version of the module in a live webserver which used ***
+ * *** older versions of the module. ***

+ * "macmartinized" polygon code copyright 1992 by Eric Haines, erich@eye.com
+ *
+ * Randy Terbush, randy@zyzzyva.com
+ * port to Apache module format, "base_uri" and support for relative URLs
+ *
+ * James H. Cloos, Jr., cloos@jhcloos.com
+ * Added point datatype, using code in NCSA's version 1.8 imagemap.c
+ * program, as distributed with version 1.4.1 of their server.
+ * The point code is originally added by Craig Milo Rogers, Rogers@ISI.Edu
+ *
+ * Nathan Kurz, nate@tripod.com
+ * Rewrite/reorganization. New handling of default, base and relative URLs.
+ * New Configuration directives:
+ * ImapMenu {none, formatted, semiformatted, unformatted}
+ * ImapDefault {error, nocontent, referer, menu, URL}
+ * ImapBase {map, referer, URL}
+ * Support for creating non-graphical menu added. (backwards compatible):
+ * Old: directive URL [x,y ...]
+ * New: directive URL "Menu text" [x,y ...]
+ * or: directive URL x,y ... "Menu text"
+ * Map format and menu concept courtesy Joshua Bell, jsbell@acs.ucalgary.ca.
+ *
+ * Mark Cox, mark@ukweb.com, Allow relative URLs even when no base specified

+/*
+ * This is module implements the TransferLog directive (same as the
+ * common log module), and an additional directive, LogFormat.
+ *
+ * The argument to LogFormat is a string, which can include literal
+ * characters copied into the log files, and '%' directives as follows:
+ *
+ * %...h: remote host
+ * %...l: remote logname (from identd, if supplied)
+ * %...u: remote user (from auth; may be bogus if return status (%s) is 401)
+ * %...t: time, in common log format time format
+ * %...r: first line of request
+ * %...s: status. For requests that got internally redirected, this
+ * is status of the *original* request --- %...>s for the last.
+ * %...b: bytes sent.
+ * %...{Foobar}i: The contents of Foobar: header line(s) in the request
+ * sent to the client.
+ * %...{Foobar}o: The contents of Foobar: header line(s) in the reply.
+ *
+ * The '...' can be nothing at all (e.g. "%h %u %r %s %b"), or it can
+ * indicate conditions for inclusion of the item (which will cause it
+ * to be replaced with '-' if the condition is not met). Note that
+ * there is no escaping performed on the strings from %r, %...i and
+ * %...o; some with long memories may remember that I thought this was
+ * a bad idea, once upon a time, and I'm still not comfortable with
+ * it, but it is difficult to see how to "do the right thing" with all
+ * of '%..i', unless we URL-escape everything and break with CLF.
+ *
+ * The forms of condition are a list of HTTP status codes, which may
+ * or may not be preceded by '!'. Thus, '%400,501{User-agent}i' logs
+ * User-agent: on 400 errors and 501 errors (Bad Request, Not
+ * Implemented) only; '%!200,304,302{Referer}i' logs Referer: on all
+ * requests which did *not* return some sort of normal status.
+ *
+ * The default LogFormat reproduces CLF; see below.
+ *
+ * The way this is supposed to work with virtual hosts is as follows:
+ * a virtual host can have its own LogFormat, or its own TransferLog.
+ * If it doesn't have its own LogFormat, it inherits from the main
+ * server. If it doesn't have its own TransferLog, it writes to the
+ * same descriptor (meaning the same process for "| ...").
+ *
+ * That means that you can do things like:
+ *
+ *
+ * LogFormat "hosta ..."
+ * ...
+ *
+ *
+ *
+ * LogFormat "hostb ..."
+ * ...
+ *
+ *
+ * ... to have different virtual servers write into the same log file,
+ * but have some indication which host they came from, though a %v
+ * directive may well be a better way to handle this.

+.SH NAME
+httpd \- Apache hypertext transfer protocol server
+.SH SYNOPSIS
+.B httpd
+[
+.B \-vX?
+] [
+.BI \-d " serverroot"
+] [
+.BI \-f " config"
+]
+.SH DESCRIPTION
+.B httpd
+is the Apache HyperText Transfer Protocol (HTTP) server process. The server may
+be invoked by the Internet daemon inetd(1M) each time a connection to the
+HTTP service is made, or alternatively it may run as a daemon.
+.SH OPTIONS
+.TP 12
+.BI \-d " serverroot"
+Set the initial value for the ServerRoot variable to \fIserverroot\fP. This
+can be overridden by the ServerRoot command in the configuration file. The
+default is \fB/usr/local/etc/httpd\fP.
+.TP
+.BI \-f " config"
+Execute the commands in the file \fIconfig\fP on startup. If \fIconfig\fP
+does not begin with a /, then it is taken to be a path relative to
+the ServerRoot. The default is \fBconf/httpd.conf\fP.
+.TP
+.B \-X
+Run in single-process mode, for internal debugging purposes only; the daemon
+does not detach from the terminal or fork any children. Do NOT use this mode
+to provide ordinary web service.
+.TP
+.B \-v
+Print the version of httpd, and then exit.
+.TP
+.B \-?
+Print a list of the httpd options, and then exit.
+.SH FILES

+/*** ***\
+
+ logresolve 1.1
+
+ Tom Rathborne - tomr@uunet.ca - http://www.uunet.ca/~tomr/
+ UUNET Canada, April 16, 1995
+
+ Rewritten by David Robinson. (drtr@ast.cam.ac.uk)
+
+ Usage: logresolve [-s filename] [-c] < access_log > new_log
+
+ Arguments:
+ -s filename name of a file to record statistics
+ -c check the DNS for a matching A record for the host.
+
+ Notes:
+
+ To generate meaningful statistics from an HTTPD log file, it's good
+ to have the domain name of each machine that accessed your site, but
+ doing this on the fly can slow HTTPD down.
+
+ Compiling NCSA HTTPD with the -DMINIMAL_DNS flag turns IP#->hostname
+ resolution off. Before running your stats program, just run your log
+ file through this program (logresolve) and all of your IP numbers will
+ be resolved into hostnames (where possible).
+
+ logresolve takes an HTTPD access log (in the COMMON log file format,
+ or any other format that has the IP number/domain name as the first
+ field for that matter), and outputs the same file with all of the
+ domain names looked up. Where no domain name can be found, the IP
+ number is left in.
+
+ To minimize impact on your nameserver, logresolve has its very own
+ internal hash-table cache. This means that each IP number will only
+ be looked up the first time it is found in the log file.
+
+ The -c option causes logresolve to apply the same check as httpd
+ compiled with -DMAXIMUM_DNS; after finding the hostname from the IP
+ address, it looks up the IP addresses for the hostname and checks
+ that one of these matches the original address.
